Question

Consider the following reaction:

2NO2(g) ⟶ N2O4(g)

Part B Calculate AG at 298 K if the partial pressures of NO2 and N204 are 0.39 atm and 1.62 atm , respectively. Express the f

science chemistry

Answer 1

Answer #1

first calculate Kp of the reaction

Kp = (P_N2O4) / (P_NO2)²

Kp = (1.62) / (0.39)² = 1.62 / 0.1521

Kp = 10.65

now

$\Delta$ G = - RTlnK

R = 8.314 J/molK

T = 298 K

K = 10.65

$\Delta$ G = - 8.314 x 298 x ln 10.65

$\Delta$ G = - 5860 J

$\Delta$ G = 5.86 kJ
