NCERT Chemistry Class 12 Chemical Kinetics - Chapter 4 Quiz 1

1. For a chemical reaction, X + 2Y → Z, if the rate of appearance of Z is 0.50 moles per liter per hour, then the rate of disappearance of Y is:
2. For the reaction, NO₂(g) + CO(g) → NO(g), the correct expression for the rate of the reaction is:
3. The rate of a reaction is primarily determined by the slowest step. This step is called:
4. The reaction of high molecularity is rare because:
5. For a chemical reaction A → B, it is found that the rate of the reaction quadruples when the concentration of A is doubled. The rate expression for the reaction is
6. On increasing the temperature of the reacting system by 10°C, the rate of reaction almost becomes double. The most appropriate reason for this is that
7. The half-life period of any first-order reaction
8. The dimensions of the rate constant of a second-order reaction involve
9. A zero-order reaction A → Products has a rate constant of 10⁻² mol L⁻¹ s⁻¹. If a process is started with 10 moles of A in a one-liter vessel, the number of moles of reactant after 10 minutes will be
10. For which of the following reactions, the temperature coefficient is maximum?
