Question

1.4. Consider the following reaction at equilibrium:
He(g)+l2 (g) 2 HI (g) AH °> 0

concentrations of the reactants and products (Motivate your answers):
(2)
1.4.1. Increasing temperature
(2)
1.4.2. Removing H2 from the mixture

Answer 1

If the reaction is endothermic as written, an increase in temperature will cause the forward reaction to occur, increasing the amounts of the products and decreasing the amounts of reactants. Lowering the temperature will produce the opposite response. A change of temperature has no effect on an athermal reaction.
