At а temperаture оf 1000K, when equilibrium is estаblished in chamber 1 fоr this reactiоn: 2SO2(g) + O2(g) ⬄ 2SO3(g) DH = -197.78 kJ/mol The quantity of each gas in the system is SO3 = 1.00 x 102 mol, SO2 = 4.15 mol, and O2 = 2.07 mol and the volume of chamber 1 is 10.0L. The pressure on the contents is increased so that the volume in chamber 2 is 1/10 the volume in chamber 1. The temperature is maintained at 1000 K. You must list any equations used, show your work, and all numbers must have units. Significant figure and rounding rules apply. f. If the temperature was reduced, how would that affect the reaction. Explain and type your answer.
