Le Chatelier's Principle

Q. 1. For the reaction: 2NH3(g) + CO2(g) ⇋ (NH2)2CO(s) + H2O(l) ΔH = -330 kJ Predict how each of the following changes would impact a reaction that is currently at equilibrium. That is, which way would the reaction progress in order to respond to the change in the system to regain equilibrium (use arrows to show the direction of change that would occur to return back to equilibrium).
