Q51 / 180 · KCET 2019 · Chemistry

Which is a wrong statement?

A
In \( \mathrm{k} \vee \mathrm{s} \frac{1}{T} \) plot is a straight line
Correct answer
B
Presence of catalyst will not alter the value of Ea
C
Rate constant \( k= \) Arrhenius constant \( A \) : if \( E a=0 \)
D
\( e^{-E a / R T} \) gives the fraction of reactant molecules that are activated at the given temp

Solution

(B)
A catalyst will alter the value of Ea.

Hence, the correct answer is option: 'B'.
