for following reaction at equilibrium if we increase the reaction temperature the equilibrium will
2SO3(g)<-->2SO2(g)+O2(g)(deltaH degrees=198kJ)
A. not shift
B.the question can not be answered because Keq is not given
C.shift to the right
D. shift to the left
I am going with D.
Do you agree?

If delta H is + (which is what I read in the post), the reaction is endothermic and can be written as
2SO3 + heat ==>2SO2 + O2
Increasing temperature will make the reaction shift so as to use up the heat which means it will shift to the right.

Actually you are 100% correct and i agree with C.
thankyou so much
