Question 1
For the reaction 2Hβ(g) + Oβ(g) β 2HβO(g), at equilibrium, [Hβ] = 0.1 M, [Oβ] = 0.02 M, what is Kc?
π‘ Hint: Recall that stoichiometry balances the change in concentrations.
Question 2
In an industrial process, the equilibrium constant for a reaction is K = 10. If the initial concentrations of reactants are 0.5 M and products are 0.1 M, predict the change needed to maximize product yield.
π‘ Hint: Use Le Chatelier's Principle to analyze how shifts work.
