Q29 / 160 · AP EAMCET 2021 (24 Aug Shift 2) · Chemistry

A catalyst is a substance which

A
changes the equilibrium concentration of the products
B
changes the energy of the reactants
Correct answer
C
shortens the time to reach equilibrium
D
changes the equilibrium constant

Solution

A catalyst decreases the activation energy of the reactants and thus, shortens the time to reach equilibrium.

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