In a reversible reaction,the energy of activation of the forward reaction is 50 kcal. The energy of activation for the reverse reaction will be.
< 50 kcal
50 kcal
Either greater than or less than 50 kcal.

half-life period of a first order reaction is 1386 s. The specific rate constant of the reaction is.
5.0 x 10-3s-1
0.5 x 10-2s-1
0.5 x 10-3s-1
In a first order reaction if k is rate constant and initial concentration of the reactant A is 0.5 M, then the half-life is.
If the rate of a reaction is equal to the rate constant, the order of the reaction is.
