THIS IS A TWO PART QUESTION. THIS IS PART 1 To investigate equilbrium a chemist mixes together sulfur dioxide, oxygen and a catalyst and compresses the gas mixture to a volume of 400cm3. The mixture is heated to a constant temperature and the reaction is allowed to reach equilibrium. The total gas volume does not change. The reaction between sulfur dioxide and oxygen to form sulfur trioxide is shown below in the balanced equation. 2SO2(g)+O2(g)2SO3(g) At equilbrium the mixture contains 0.0540molSO2 and 0.0270mol2. At the temperature used, the value for Kc is 3.045104dmmor1. Write the expression for Kc and the units of Kc for this equilibrium. Kc=[SO3]2/[SO2]2[O2] a. Units =mol1dm3 Kc=[SO3]2[SO2]2[O2] b. Units =mol1dm3 c.Kc=[SO3]2[SO2]2/[O2]Kc=[SO3]2/[SO2]2[O2]d.Units=mol2dm6Kc=[SO2]2[O2]/[SO3]2e.Units=mor2dm3
