Consider the following equation: $$2 \mathrm{SO}_2(g)+\mathrm{O}_2(g) \rightleftharpoons 2 \mathrm{SO}_3(g), \Delta H=-190 \mathrm{~kJ} $$ The number of factors which will increase the yield of $\displaystyle \mathrm{SO}_3$ at equilibrium from the following is $\displaystyle \_\_\_\_$ A. Increasing temperature B. Increasing pressure C. Adding more $\displaystyle \mathrm{SO}_2$ D. Adding more $\displaystyle \mathrm{O}_2$ E. Addition of catalyst
