2SO2(g) + O2(g) ⇌ 2SO3(g) 평형에서 온도 증가
Consider the following exothermic reaction at equilibrium:
2SO2(g) + O2(g) ⇌ 2SO3(g)
2SO2(g) + O2(g) ⇌ 2SO3(g) ... ΔH° = –99 kJ/mol
Le Chatelier’s principle predicts that
an increase in temperature will result in (__).
a. no changes in equilibrium partial pressures
b. an increase in Keq
c. a decrease in the partial pressure of O2
d. a decrease in the partial pressure of SO2
e. a decrease in the partial pressure of SO3

ΔH° < 0 이므로,
발열 반응 (exothermic reaction).
발열 반응에서 열(Q)은 생성물
2SO2(g) + O2(g) ⇌ 2SO3(g) + Q
( 참고 https://ywpop.tistory.com/2691 )
발열 반응에서,
온도 증가 = 생성물 추가 이므로,
역반응이 일어난다.
답: e. a decrease in the partial pressure of SO3
