For the reaction 2NO2(g)⇌N2O4(g),2{NO}_{2} ( g ) ⇌ {N}_{2}{O}_{4} ( g ) , when ΔS=−176.0JK−1\Delta S = - 176 . 0J{K}^{- 1} and ΔH=−57.8kJmol−1\Delta H = - 57 . 8kJ{mol}^{- 1} the magnitude of ΔG\Delta G at 298K298K for the reaction is _____ kJmol−1{kJmol}^{- 1}. (Nearest integer)

Correct answer

0

Step-by-step solution

ΔG=ΔH−TΔS\Delta G = \Delta H - T \Delta S

=−57.8−298(−176.0)1000=−57.8+52.448=−5.352KJmol−1= - 57 . 8 - \dfrac{298 ( - 176 . 0 )}{1000} = - 57 . 8 + 52 . 448 = - 5 . 352KJ{mol}^{- 1}
