If \( K_c = 49 \) for this reaction, what is the equilibrium concentration of HI? \[ \text{H}_2(g) + \text{I}_2(g) \rightleftharpoons 2\text{HI}(g) \]2. **Multiple Choice Question:** - Which of the following is true for a system whose equilibrium constant is much smaller than one? a. The reaction mixture contains mostly reactants at equilibrium. b. The reaction mixture contains mostly products at equilibrium. c. The rate of reaction is very slow. d. The moles of reactants and products are relatively similar at equilibrium. e. Both A and C.

Formula used : Molarity = moles /volume Equilibrium constant = [products]/[reactants]
