### Response of Equilibria to Change in CR pg. 138

On page 138 in the Course Reader, we are given the example $N^{_{2}}(g) + 3H_{2}(g) \leftrightharpoons 2NH_{3}(g)$. Could you please explain what happens if H2 is decreased and why? Thank you!

If H2 is decreased then the equation shifts to the left in order to go back to equilibrium. This is because if the H2 concentration in the reaction decreases, then the product side of the equation (NH3) must begin to dissociate more readily in order to increase the concentration of the reactants and bring the system back to the original equilibrium constant. The system therefore [censored] towards the reactants when one of the reactant concentrations is decreased.
