a) Explain Le Chtelier's Principle. b) Given the reaction: 2SO2(g)+O2(g)2SO3(g)+250J What would happen if i) the temperature were to increase? ii) the pressure were to increase? Knowing that the concentration of silver ions, Ag+, in a solution of silver chromate, Ag2CrO4, is 1.5104M, and that there is some solid silver chromate present in the solution as well, calculate the Ksp of silver chromate
