Solution

Q.
The standard enthalpy and standard entropy of decomposition of $N_{2} O_{4}$ to $N O_{2}$ are 55.0 kJ ${mol}^{- 1}$ and 175.0 $J / K / mol$ respectively. The standard free energy change for this reaction at $25 ° C$ in J ${mol}^{- 1}$ is _____ (Nearest integer). [2025]

Ans.
(2850)

$Δ G ° = Δ H ° - T Δ S °$

$Δ G ° = 55 {kJ mol}^{- 1} - 298 K \times 175 {JK}^{- 1} {mol}^{- 1}$

$Δ G ° = 55000 {J mol}^{- 1} - 298 K \times 175 {JK}^{- 1} {mol}^{- 1}$

$Δ G ° = 55000 {J mol}^{- 1} - 52150 {J mol}^{- 1}$

$Δ G ° = 2850 {J mol}^{- 1}$
