3H2(g) + N2(g) reverse reaction arrow 2NH3(g)
What factors would affect the equilibrium constant for the reaction above? (Select all that apply.)
increasing the H2 concentration decreasing the NH3 concentration increasing the temperature
decreasing the temperature
increasing the pressure
decreasing the pressure
adding a catalyst
**I thought the answer was the first six (all except the catalyst, but I got it wrong...)

The answer is only temperature changes. The equilibrium constant becomes larger with a temperature change, the forward reaction is favored and the eq. shifts to the right. If the constant becomes smaller, the reverse reaction is favored and shifts to the left.
