The enthalpy and entropy change for the reaction ${Br}_{2} (l) + {Cl}_{2} (g) \to 2 BrCl (g)$ are $30 k J m o l^{- 1}$ and $105 J K^{- 1} m o l^{- 1}$ respectively. The temperature at which the reaction will be in equilibrium is

Options:

Answer:

Solution:

We know that

$∆ G = ∆ H - T ∆ S$

When the reaction is in equilibrium, $∆ G = 0$

$0 = ∆ H - T ∆ S \Rightarrow T = \frac{∆ H}{∆ S}$

$T = \frac{30 \times 1000}{105} = 285.7 K$
