The decomposition reaction of copper(II) oxide is given by:

4 CuO(s) 2 Cu2O(s) + O2(g)

Determine the standard enthalpy of the reaction, knowing that the equilibrium vapor pressures of O2 are 15.4 mmHg at 600C and 927 mmHg at 850C.

Tick the correct alternative:

Choose an option:

a) rH = 1.34 x 105 J mol-1

b) rH = - 13400 J mol-1

c) rH = - 13.4 kJ mol-1

d) rH = 1.34 x 105 kJ mol-1
