For the reaction 2 NO 2 ( g ) ⇌ N 2 O 4 ( g ) , when ΔS = - 176 . 0 J K - 1 and ΔH = - 57 . 8 kJ mol - 1 the magnitude of ΔG at 298 K for the reaction is _____ kJmol - 1 . (Nearest integer)
Correct answer
0
Step-by-step solution
ΔG = ΔH - TΔS = - 57 . 8 - 298 ( - 176 . 0 ) 1000 = - 57 . 8 + 52 . 448 = - 5 . 352   KJ   mol - 1 The Magnitude of ∆ G   to   the   nearest   integer   is   5 .
