An increase in temperature will create what type of shift in the following equation: 2SO3 = 2SO2+ O2 delta H = +197 kJ/mol?
Wouldn't it be a shift right because there is heat involved?
Since dH is +, I include that in the equation this way.
2SO3 + heat ==> 2SO2 + O2
So an increase in heat causes the reaction to get rid of the heat and it fcan do that by shifting to the right. That's the way to use up the added heat. You're right. But if you cool it (take heat away) it will shift to the left (so as to replace the heat we took away).
