Consider the following chemical reaction. 2HgO(s)2Hg(s)+O2(g) The enthalpy change is +182kJ. Answer the following questions. Show your work to earn points. 1) When you add O2(g), will the chemical equilibrium shift? If so, in which direction? 2) When you add Hg(s), will the chemical equilibrium be shift? If so, shift left or right? 3) When you decrease pressure, will the chempical equilibrium shift? If so, in which direction? 4) When you cool the reaction, will the chemical equilibrium shift? If so, shift left or right
