Problem
For the endothermic gas-phase equilibrium H2(g)+I2(g)⇌2HI(g) a sealed reaction vessel is at equilibrium. The following two stresses are applied in the order listed:
1. Some H2 is removed.
2. The temperature is increased.
State the overall direction in which the equilibrium shifts after both stresses have occurred (toward reactants, toward products, or no net shift).
