Question

The rate constant of a reaction depends on

• A. temperature
• B. initial concentration of the reactants
• C. time of reaction
• D. extent of reaction

Answer 1

Answer: (A)

temperature

Answer 2

The rate constant (k ) of all chemical reactions depends on temperature.
$k=Ae^{E_a/RT}$
where, A = pre-exponential factor, $E_a$ = activation energy.
