Document Summary
No observable reactions because forward and reverse at the same time. If k >> 1 reverse reaction is favored (more reactants than products) neither direction is favored (forward reaction goes forward reaction is favored (more products than reactants) If k is less than 1 it means large denominator. If k is greater than 1 it means small denominator: write the equilibrium constant expressions, k, and predict the position of equilibrium for the following. 2 so2(g) + o2(g)to 2 so3(g) k = 8 x 1025. N2(g) + 2 o2(g) to 2 no2(g) K = 3 x 10 17 temperature is the only thing that changes k: rewriting reactions, when answering questions about changing equations ask yourself two questions. Does it have the correct coefficient: compute the equilibrium constant at 25 c for the reaction nh3(g) 0. 5 n2(g) + When n2+3h2 to 2nh3 has an equilibrium constant of 3. 7*10^3.
