Question

Predict the following reaction, whether its spontaneous or nonspontaneous:

a.) 2NaOH (s) + CO2 (g) ---> Na2CO3 (s) + 2H2O (l)

b. 2Fe (s) + 3H2O (g) ---> Fe2O3 (s) + 3H2 (g)

Answer 1

Answer: a) $2NaOH (s) + CO_2 (g) ---> Na_2CO_3 (s) + 2H_2O (l)-$ spontaneous;

b)$2Fe (s) + 3H_2O (g) ---> Fe_2O_3 (s) + 3H_2 (g) -$nonspontaneous.
