Chapter 13, Problem 13.74SP

Gaseous indium dihydride is formed from the elements al elevated temperature:

In(g) + H₂(g) ⇌ InH₂(g) K_p = 1.48 at 973 K

Partial pressures measured in a reaction vessel are: P_In = 0.0600 atm, $P_{{\text{H}}_{\text{2}}}=0.0350\text{atm}$, $P_{{\text{InH}}_{\text{2}}}=0.0760\text{atm}$.

1. (a) Calculate Q_p, and determine the direction of reaction to attain equilibrium.
2. (b) Determine the equilibrium partial pressures of all the gases.
