16.4 Exercise 16

Consider the following reaction at 298 K:
$\text{N}_{2} \text{O}_{4} \left(g\right) \rightleftharpoons \text{2NO}_{2} \left(g\right) K_{P} = 0.142$

What is the standard free energy change at this temperature? Describe what happens to the initial system, where the reactants and products are in standard states, as it approaches equilibrium.
