Chemistry - Thermodynamics - I Question with Solution | TestHub

${\text{Br}}_2\left(l\right)+{\text{Cl}}_2\left(\text{g}\right)\to 2\text{BrCl}\left(\text{g}\right)$

$\Delta \text{H}=30\text{ kJ}{\text{ mol}}^{-1}\text{, }\Delta \text{S}=105{\text{ J K}}^{-1}{\text{mol}}^{-1}$

$\Delta \text{S}=\frac{\Delta \text{H}}{\text{T}}$i.e.,$105=\frac{30}{\text{T}}\times 1000$

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