The enthalpy and entropy change for the reaction   B r 2 (l)+C l 2 (g)→2BrCl(g) are   30 kJ mo l −1   and  105 J K −1  mo l −1  respectively. The temperature at which the reaction will be in equilibrium is                                

Options:

Answer:
A
Solution:

We know that   ΔG=ΔH−TΔS When the reaction is in equilibrium,   ΔG=0   0=ΔH−TΔS⇒T= ΔH ΔS T= 30×1000 105 =285.7 K
