Gaseous sulfur trioxide decomposes into gaseous sulfur dioxide and oxygen gas. a. Write and balance the reaction. b. When 0.500atm of sulfur trioxide is allowed to reach equilibrium at 1000K,0.200atm of sulfur trioxide are present at equilibrium. What is the value of Kp for this reaction? c. Describe three ways to decrease the decomposition of sulfur trioxide. 8. Use the reactions and their equilibrium constants to predict the equilibrium constant for the reaction 2A(s)3D(g). A(s)1/2B(g)+C(g)3D(g)B(g)+2C(g)K1=0.0334K2=2.35
