For the reaction in problem (2) calculate the degree of dissociation

alpha= (number of moles of PCI, dissociated at equilibrium) / (original number of moles of PCs in the system)

at T = 400 K and P = 1 atm. Assume that in the conditions of the problem the equilibrium gas mixture behaves as an ideal gas mixture.

O a. 0.97

O b.0.87

O c. 0.15

O d. 0.051

O e. 3.51
