Which of the following statement about the catalyst is/are true?

Options

A. A catalyst accelerates the rate of reaction by bringing down the energy of activation
B. A catalyst does not participate in reaction mechanism
C. A catalyst makes the reaction more feasible by making `DeltaG` more negative
D. A catalyst makes equilibrium constant more favourable for forward reaction

Answer

A

Explanation

For a zero order reaction, `t_(1//2)prop [A]` hence doubling the concentration doubles the `t_(1//2)`
