Which of the following concepts are correct
(A) If for, \( \mathrm{A} \rightarrow \mathrm{B} \quad \Delta \mathrm{H}=+\mathrm{q} \) cal
\( \mathrm{P} \) then for, \( \mathrm{B} \rightarrow \mathrm{A} \Delta \mathrm{H}=-\mathrm{qcal} \)

W
(B) If for, A \( \rightleftharpoons \) B equilibrium constant \( =\mathrm{K} \) then for, \( \mathrm{B} \longrightarrow \) A equilibrium constant \( =\frac{1}{\mathrm{~K}} \)
(C) If for, \( \mathrm{A} \rightarrow \mathrm{B} \) rate constant \( =\mathrm{k} \) then for, \( \mathrm{B} \rightarrow \mathrm{A} \) rate constant \( \neq \mathrm{k} \)
(D) If for, \( A \rightarrow B \) energy of activation \( =E \) then for, \( \mathrm{B} \rightarrow \mathrm{A} \) energy of activation \( =-\mathrm{E} \)
