Question

The enthalpy and entropy change for the reaction $Br_2(l) + Cl_2 (g) \rightarrow 2BrCl (g)$ are 30kJ mol⁻¹ and 105 JK⁻¹ mol⁻¹ respectively. The temperature at which the reaction will be in equilibrium is
(a) 273 K
(b) 450 K
(c) 300 K
(d) 285.7 K

Answer 1

Heya Dude!

Option is (b) 450 K

Hopes help ya

Answer 2

Answer:

285.7

Explanation:

ΔH=30 KJ/mol

ΔS=105 J/K mol

ΔS=ΔH/T

T=30×1000 J÷105

=285.7
