FAQs on Past Year Paper, Chemistry (Set - 3), 2016, Class 11, Chemistry - Additional Study Material for NEET

1. What is the definition of a chemical reaction?
Ans. A chemical reaction is a process in which one or more substances (reactants) are transformed into one or more different substances (products) through the breaking and forming of chemical bonds.
2. How is the rate of a chemical reaction determined?
Ans. The rate of a chemical reaction is determined by measuring the change in concentration of either the reactants or the products over a specific period of time. This can be done by monitoring the appearance or disappearance of a characteristic property, such as color or gas evolution.
3. What is the difference between endothermic and exothermic reactions?
Ans. Endothermic reactions absorb heat energy from the surroundings, resulting in a decrease in temperature. On the other hand, exothermic reactions release heat energy to the surroundings, causing an increase in temperature. In endothermic reactions, the energy of the products is higher than that of the reactants, while in exothermic reactions, the energy of the products is lower than that of the reactants.
4. What factors can affect the rate of a chemical reaction?
Ans. Several factors can affect the rate of a chemical reaction, including temperature, concentration of reactants, surface area, presence of catalysts, and pressure (for gas reactions). Increasing the temperature, concentration, or surface area generally increases the rate of the reaction. Catalysts can also speed up the reaction by providing an alternative pathway with lower activation energy.
5. What is the significance of balancing chemical equations?
Ans. Balancing chemical equations is important because it ensures that the law of conservation of mass is obeyed. A balanced equation shows that the same number of atoms of each element is present on both sides of the equation, indicating that no atoms are created or destroyed during the reaction. It also allows for the calculation of stoichiometric ratios, which are essential for determining the amount of reactants needed or products obtained in a chemical reaction.
