When a catalyst increases the rate of a chemical reaction, the rate constant

Options

A. remains constant
B. increase
C. decrease
D. may increase or decrease depending on the order of fraction

Answer

B

Explanation

Rate = K (Reactant)
In the presence of catalyst at the same concentration of the reactant as rate, `k` increases Alternatively : `k= Ae^(-Ea//RT)` in the presence of catalyst at the same temperature, Ea decreases
Hence, `l` increases.
