Which of the following statements are in accordance with the Arrhenius equation?

Answer»

Rate of a reaction increases with INCREASE in temperature
Rate of reaction increases with decreases in ACTIVATION energy
Rate constant decreases exponentially with increase in temperature
Rate of reaction decreases with decrease in activation energy.

Solution :rrhenius equation ,K=`Ae^(-(E_(a))/(RT))`
So (A) `kprop e^(-(1)/(T))`
`therefore` Rate `rpropT`
TEMPERATUE increase than the rate of reaction increase.
(b)In Arrhenius equation `k prop e^(-E_(a))`
So, `k prop(1)/(E_(a))`
If energy of activation decreases than rate of reaction increases.
