Question

Express the relationship between the rate of production of water and the rate of disappearance of oxygen in the following reaction:
$C_{2} H_{6} (g) + \frac{7}{2} O_{2} (g) \to 2 {CO}_{2} (g) + 3 H_{2} O (l)$

Solution

The relationship between the rate of production of water and the rate of disappearance of oxygen can be express as:

Rate = + \frac{1}{3} \frac{d [H_{2} O]}{dt} = - \frac{2}{7} \frac{d [O_{2}]}{dt}
