The following thermochemical equation is for the reaction of sulfur dioxide(g) with oxygen(g) to form sulfur trioxide(g). 2SO2(g) + O2(g)2SO3(g) H = -198 kJ How many grams of SO2(g) would have to react to produce 31.9 kJ of energy?
For the equilibrium reaction 2SO2(g) + O2(g) 2SO3(g), delta Hrxn = -198 kJ/mol. Which one of these factors would cause the equilibrium constent to increases? Decrease the temperature. Add SO2 gas Remove O2 gas Add a catalyst. None of these Consider this reaction at equilibrium If the volume of the system is compressed at constent temperature, what change will occure in the position of the equilibrium?
