Answer

Explanation:

Step1: Identify the given reactions

We have: $C_3H_8(g)+3H_2O(g)\rightleftharpoons3CO(g) + 7H_2(g)$ $CO(g)+H_2O(g)\rightleftharpoons CO_2(g)+H_2(g)$

Step2: Multiply the second - reaction by 3 to balance CO

The second reaction becomes $3CO(g)+3H_2O(g)\rightleftharpoons3CO_2(g)+3H_2(g)$

Step3: Add the two reactions

Add $C_3H_8(g)+3H_2O(g)\rightleftharpoons3CO(g) + 7H_2(g)$ and $3CO(g)+3H_2O(g)\rightleftharpoons3CO_2(g)+3H_2(g)$ $C_3H_8(g)+3H_2O(g)+3CO(g)+3H_2O(g)\rightleftharpoons3CO(g)+7H_2(g)+3CO_2(g)+3H_2(g)$ Cancel out the $3CO(g)$ on both sides.

Answer:

$C_3H_8(g)+6H_2O(g)\rightleftharpoons3CO_2(g)+10H_2(g)$
