1) Consider again the definition of Keq. The concentrations of products appear in the numerator, and the concentrations of reactancs appear in the numerator. If Keq increases, the concentrations of products must increase.
2) Correct
3) Apply Le Chatelier's principle here. The forward reaction is exothermic and it also decreases the number of moles in a fixed volume. To increase yield, you want to favor the forward reaction. Increasing temperature and decreasing pressure favors the REVERSE reaction, by tending to compensate for the temperature rise (absorbing heat) and pressure decrease (producing more moles)
