Problem 13.48

The chemical reaction for the dissociation of nitrogen tetroxide is 

N₂O₄(g) → 2NO₂(g)

The reported standard-state Gibbs energy change for this reaction over a limited temperature range is

for the pure component, ideal gas at 1 bar standard state and T in kelvins. 

a. What is the standard-state heat of reaction for the dissociation of nitrogen tetroxide? 

b. Determine the equilibrium composition of this mixture at 50°C and 0.1, 1, and 10 bar. 

c. Repeat the calculation at 200°C.
