In which of the following, `E_(a)` for backward reaction is greater than `E_(a)` for forward reaction?

The E_a for forward reaction is 50 kcal. The E_a for its backward reaction is:

The E_a for forward reaction is 50 kcal. The E_a for its backward reaction is:

Assertion: A reaction 2SO_(2)+O_(2)hArr2SO_(3) , has K_(p) at 298 K and 500 K as 4.0xx10^(24 and 8.5xx10^(10) respectively. Reason: The E_(a) for the forward reaction is lesser than E_(b) for the backward reaction.

What is the sign of DeltaH , when activation energy of a backward reaction is more than that of the forward reaction?

Statement-1: In a reversible endothemic reactiuon, E_(act) of forward reaction is higher than that of backward reaction. Statement-2: The threshold energy of forward reaction is more than that of backward reaction.

At a given temperature, for the reaction AhArrB , the rate constant (k_(f)) of the forward reaction is greater than that of the backward reaction (k_(b)) . Is the value of equilibrium constant (K) for this reaction greater than, less than or equal to 1?

When rate of backward reaction is equal to rate to rate of reaction , the stage is called when rate of backward reaction is equal to rate of forward reaction , the stage is called _____.
