Question

What is the ΔS_univ for the following reaction at 25°C? N₂(g)+ 3H₂(g)⇌ 2NH₃(g)ΔS_sys = -197 J/K;ΔH_sys = -91.8 kJ

Quizplus · Accepted Answer

The correct answer is A because the ΔS_univ is equal to the ΔS_sys + ΔS_surr. The ΔS_surr is equal to -ΔH_sys/T. Therefore, the ΔS_univ is equal to -197 J/K + (-(-91.8 kJ)/298 K) = 111 J/K.
