The following reaction is endothermic in the forward direction. NH4Cl(s) <->NH3(g) + HCl(g) For each of the following cases, briefly explain whether the action causes net reaction from left to right, right to left, or no net reaction. Also, state whether the equilibrium partial pressure of NH3 increases, decreases or stays the same. (a) increasing the temperature; (b) transferring the equilibrium mixture to a larger reaction vessel; (c) adding a small amount of LiOH(s), which reacts with HCl to give LiCl(s) and H2O(l
