Read the case study given below and answer the questions that follow:
Available water resources are degrading rapidly. The major rivers of the country generally retain better water quality in less densely populated upper stretches in hilly areas. In plains, river water is used intensively for irrigation, drinking, domestic and industrial purposes. The drains carrying agricultural (fertilizers and insecticides), domestic (solid and liquid wastes), and industrial effluents join the rivers. The concentration of pollutants in rivers, especially remains very high during the summer season when flow of water is low. The Central Pollution Control Board (CPCB) in collaboration with State Pollution Control Boards has been monitoring water quality of national aquatic resources at 507 stations. The data obtained from these stations show that organic and bacterial contamination continues to be the main source of pollution in rivers. The Yamuna river is the most polluted river in the country between Delhi and Etawah. Other severely polluted rivers are: the Sabarmati at Ahmedabad, the Gomti at Lucknow, the Kali, the Adyar, the Cooum (entire stretches), the Vaigai at Madurai and the Musi of Hyderabad and the Ganga at Kanpur and Varanasi. Ground water pollution has occurred due to high concentrations of heavy/toxic metals, fluoride and nitrates at different parts of the country.
 
Q. Why the available water resources are degrading rapidly?
  • a)
    Border conflicts
  • b)
    Concentration of pollutants is very high
  • c)
    Drying up of water bodies
  • d)
    None of the Above
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Read the case study given below and answer the questions that follow:A...
Water pollution happens when toxic substances enter water bodies such as lakes, rivers, oceans and so on, they get dissolved in them and lie suspended in the water or get deposited on the bed. This degrades the quality of water.

Reasons for the rapid degradation of available water resources:
- Concentration of pollutants is very high: The major reason for the rapid degradation of available water resources is the high concentration of pollutants in rivers. These pollutants come from various sources such as agricultural runoff (fertilizers and insecticides), domestic waste (solid and liquid waste), and industrial effluents. During the summer season when the flow of water is low, the concentration of pollutants in rivers increases significantly, leading to water quality degradation.
- Intensive use of river water: In the plains, river water is used intensively for various purposes including irrigation, drinking, domestic, and industrial uses. This intensive use puts pressure on the rivers and contributes to their degradation.
- Groundwater pollution: Groundwater pollution has also occurred in various parts of the country due to high concentrations of heavy/toxic metals, fluoride, and nitrates. This further adds to the degradation of available water resources.
- Monitoring and data: The Central Pollution Control Board (CPCB) and State Pollution Control Boards have been monitoring the water quality of national aquatic resources at 507 stations. The data obtained from these stations show that organic and bacterial contamination continue to be the main sources of pollution in rivers.
In conclusion, the degradation of available water resources is primarily due to the high concentration of pollutants in rivers, intensive use of river water, groundwater pollution, and lack of effective management and monitoring. Addressing these issues through better pollution control measures and sustainable water management practices is essential to prevent further degradation of water resources.

Ground water pollution has occurred due to high concentrations of heavy/toxic metals, fluoride and nitrates at different parts of the country.Q. Why does the concentration of pollutants in rivers, especially remains very high during the summer season?

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Reactions can occur at different speeds.Reason: Rate of reaction is also called speed of reaction.
