想問這題的（3）為什麼減少溫度會往左呢？不是應該往右嗎？

10.
Ans
=
In the equilibrium 2SO2(g) + O2(g)
following can increase the concentration
(1) Increase the pressure
(2) Reduce the pressure
(3) Reduce the temperature
(4) Add O2(g)
2SO3(g) + Heat, which of the
of SO2(g)?
(-)
(1) Increase the pressure, move to theright, the wncentration of SO2(g)
increases.
(2) Reduce the pressure, move to the left, the wncentration of SO2(g)
decreases.
(3) Reduce the temperature, move to the left, the wncentration of SO2(g)
increases.
(4) Add O2(g), move to the right, the wncentration of SO2(g) increases.

往右是放熱反應溫度會升高，反過來說降溫會吸收熱量，故反應向左
