Question
Plots showing the variation of the rate constant $$(k)$$ with temperature $$(T)$$ are given below. The plot that follows Arrhenius equation is
A.
B.
C.
D.
Answer :
Solution :
As per Arrhenius equation $$\left( {k = A{e^{ - {E_a}/RT}}} \right),$$ the rate constant increases exponentially with temperature.
