Answer to Question #68528 in Physical Chemistry for yeeyun

Question

An experimenter places 15.0 mol of A and 18.0 mol of B in a container. The container is heated to 600 K, and gas phase equilibrium is established, with:
A+B ⟺2C+3D

The equilibrium mixture is found to have pressure 1085 torr and to contain 10.0 mol of C. Evaluate the value of K°p and ΔG°p at 600 K, assuming ideal gases.
