I’m not 100% sure but I think so
There should be 76.3 if not search it up and it’ll say
5 degrees because five - 5=0 which is where you need to get to
The effects on the concentration of SO3 gas when the
following changes occur after initial equilibrium has been established in this
system (N.C. = no change) by adding a catalyst.
2SO2(g) + O2(g) 2SO3(g) + 46.8 kcal
So that even though there is an addition of catalyst, no
change in reactants or products has occurred because catalyst only provides a
faster pathway for the reaction to occur.
