Question

$K_p$ for the following reaction will be equal to
$ Fe(s) + H_2O (g)\ce{<=>} Fe_3O_4(s) +H_2(g)$

• A. $\frac{\left(p_{H_2}\right)^{4}\left(p_{Fe_3O_4}\right)}{\left(P_{Fe}\right)^{3}\left(p_{H_2O}\right)^{2}}$
• B. $\frac{\left(p_{H_2}\right)}{\left(P_{H_2O}\right)}$
• C. $\frac{\left(p_{H_2}\right)^{4}}{\left(P_{H_2O}\right)^{4}}$
• D. $\frac{\left(p_{H_2}\right)\left(p_{Fe_3O_4}\right)}{\left(P_{Fe}\right)}$

Answer 1

Answer: (C)

Correct answer is (c) $\frac{\left(p_{H_2}\right)^{4}}{\left(P_{H_2O}\right)^{4}}$
