Question

For each of the following reactions, calculate H rxn, S rxn, and G rxn at 25C.
Part I 3H2(g) + Fe2O3(s) --> 2Fe(s) + 3H2O(g)
H rxn
Part J S rxn
Part K G rxn
Part L State whether or not the reaction in part I is spontaneous. If the reaction is not spontaneous, would a change in temperature make it spontaneous? If so, should the temperature be raised or lowered from 25C? For each of the following reactions, calculate H rxn, S rxn, and G rxn at 25C.
Part I 3H2(g) + Fe2O3(s) --> 2Fe(s) + 3H2O(g)

Part J S rxn
Part K G rxn

Explanation / Answer

Here H values should be given for each reactants and product.

Then you can calculate delta H,(H value of product- H value of reactants)

Delta S can be caculated, = (delta H/ T)

Delta G can be calculated,

delta G = delta H - T delta S
