# Solution: Consider the following reaction:   2NOBr(g) ⥫⥬ 2NO(g) + Br 2(g)      K = 0.42 at 373 KGiven that S° of NOBr(g) = 272.6 J/mol·K and that ΔS°rxn and ΔH°rxn are constant with temperature, find(a) ΔS°rxn at 298 K

###### Problem

Consider the following reaction:

2NOBr(g) ⥫⥬ 2NO(g) + Br 2(g)      K = 0.42 at 373 K

Given that S° of NOBr(g) = 272.6 J/mol·K and that ΔS°rxn and ΔH°rxn are constant with temperature, find

(a) ΔS°rxn at 298 K
