Practice Problem 8

Predict whether the following reaction is still spontaneous at 500C:

N2(g) + 3 H2(g) equilibr.gif (63 bytes) 2 NH3(g)

Assume that the values of  deltaHo and deltaS used in Practice Problem 7 are still valid at this temperature.


deltaGo = 61.4 kJ, the reaction is unfavorable at high temperatures.
