Directions : In the following questions, A statement of Assertion (A) ...
Explanation:

Assertion: In the laboratory, a solution of a desired concentration is prepared by diluting a stock solution.

Reason: Stock solution is the solution of higher concentration.

The correct answer is option 'A' - Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Explanation:
To understand the given assertion and reason, let's break it down into two parts:

1. Assertion: In the laboratory, a solution of a desired concentration is prepared by diluting a stock solution.

In a laboratory, when a solution of a specific concentration is required, it is prepared by diluting a stock solution. Dilution involves adding a solvent (usually water) to the stock solution to decrease its concentration.

2. Reason: Stock solution is the solution of higher concentration.

A stock solution refers to a solution that has a higher concentration compared to the desired concentration. It is typically a concentrated solution that is used as a source for preparing solutions of lower concentration.

Explanation of the Assertion and Reason:

The given assertion and reason are both correct and are interrelated. A stock solution is prepared to have a higher concentration so that it can be diluted to obtain solutions with different desired concentrations.

When a solution of a desired concentration needs to be prepared in the laboratory, the stock solution is used as a starting point. By diluting the stock solution with a suitable solvent, the desired concentration can be achieved.

Conclusion:

The given assertion and reason are logically correct and are connected to each other. The stock solution is prepared to have a higher concentration, and from that, solutions of desired concentrations are obtained by dilution. Therefore, option 'A' - Both Assertion and Reason are correct and Reason is the correct explanation for Assertion is the correct answer.

Directions : In the following questions, A statement of Assertion (A) ...
Correct option is A
The stock solution is the solution of higher concentration. Therefore in the laboratory, a solution of the desired concentration is prepared by diluting a stock solution.
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Hence, option A is correct

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: Rate of reaction is a measure of change in concentration of reactant with respect to time.Reason: Rate of reaction is a measure of change in concentration of product with respect to time.
