What is the ΔSuniv for the following reaction at 25°C?
N2(g) + 3H2(g) ⇌ 2NH3(g) ΔSsys = -197 J/K; ΔHsys = -91.8 kJ
PLEASE SHOW WORK
ΔSuniverse = ΔSsystem + ΔSsurroundings
System is the
reaction
ΔSsystem = -197 J/K
ΔSsurrounding = -ΔH/T
= -(-91800J/298 K)
ΔS Universe = -197 J/K + (91800J/298 K)
= 111.05 J/K
