Conversion rate α=Q/? H=78.4/98=80%
B. Gas irrelevant to the reaction is charged at constant volume, and the positive and negative reaction rates are constant and the balance is constant.
C. 1molSO3 is completely equivalent to 1molSO2 and 0.5molO2, while Q 1+Q2=? H
Q 1=98-78.4= 19.6
D. K of the reaction can be calculated according to the conversion rate, and then Q can be calculated by using the value given by the D option. By comparing the relative sizes of q and k, it can be judged. Pay attention to Mr. Guo, an elite chemistry teacher with determination when calculating.
