Consider the reaction:

Determine the product temperature if the reaction is adiabatic process, complete, and the pressure is at 1 bar.

Consider the following conditions :

a) Both reactants are in reduced temperature > 25C and in stoichiometric quantities.

b) Both reactants are in reduced temperature at 25C and in stoichiometric quantities.

c) Both of the reactants are in reduced temperature at 25C; one of the reactants is in excess. Note: create two calculations to determine which is the excess.

c.1) which of the reactants is in excess?

Please help me, i will give upvote if answers are all correct. Thank you!
