Concept introduction:
According to Le Chatelier’s principle, if equilibrium is disturbed by changing the number of moles, pressure and temperature, the equilibrium will shift to remove the disturbance. For example, if number of moles or pressure of reactant is increased, the reaction will shift in forward direction to decrease the number of moles or pressure of the reactant.
If temperature is increased, the reaction moves to forward direction for an endothermic reaction and it moves to backward direction for exothermic reaction.

Consider the following general reaction:2A(g) + 2B(g) ⇌ 3C(g)
The reaction was measured to have an equilibrium reaction constant (K) of 0.0100 at 100 K. If the reaction has a standard enthalpy change (ΔHrxn) of 500.3 J/mol, what should the equilibrium reaction constant be when the temperature is 800 K? (Please provide your answer to 3 significant figures.)
For which of these reactions will there be no effect on the relative amounts of the substances present at equilibrium
when the pressure of the system is increased at constant temperature?
