Question

For a zero order reaction
(A) The rate of the reaction is independent of reactant concentration
(B) The rate constant is independent of temperature
(C) The rate constant of the reaction is independent of reactant concentration
(D) Thermal decomposition of HI on gold surface is a zero order reaction
Choose the correct feature(s) from the options given below:

• A. (A) only
• B. (A) and (B) only.
• C. (A), (C) and (D) only.
• D. (B) and (C) only.

Hint:

Zero-order reactions occur when the concentration of reactants has no effect on the rate of reaction.

Answer 1

The Correct Option is C

In a zero-order reaction, the rate is independent of reactant concentration (A). The rate constant may or may not depend on temperature, but the reaction is typically independent of concentration (C).
