Hydrogen and fluorine react to form hydrogen fluoride, like this: H2(g)+F2(g)2HF(g) The reaction is exothermic. Suppose a moxture of H2,F2 and HF has come to equilibrium in a closed reaction vessel, Predict what change, if arvy, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decige whether the equilibrium shifts to the right or left
