For the reaction 2NO2 (g) hArr N2O4(g), ...

For the reaction `2NO_2 (g) hArr N_2O_4(g)`, when `DeltaS = - 176.0 J K^(-1) and DeltaH = - 57. 8 kJ mol^(-1)`, the magnitude of `Delta G` at 298 K for the reaction is __________ kJ `mol^(-1)`. (Nearest integer)

Text Solution

Verified by Experts

The correct Answer is:
5
`DeltaG = DeltaH - T DeltaS`
`DeltaG = 57.8 - (298(-176))/(1000)`
`DeltaG = - 5.352 kJ//" mole"`
[Nearest integer value] = 5.
