The catalyst would increase the rate of the forward reaction...
And increase the rate of the backward to the same extent thus not affecting equilibrium.
Movement that's what it is
Answer:
818.6 KJ/mol
Explanation:
2Al(s) + 3H2O(l) → Al2O3(s) + 3H2(g)
∆H=∆Hp-∆Hr
∆H=(1(∆HAl2O3)+3(∆HH2))-(2(∆HAl)+3(∆HH2O))
∆H=((-1676.0 KJ/mol)+3(0 KJ/mol))-(2(0 KJ/mol)+3(-285.8 KJ/mol))
∆H=-818.6 KJ/mol
