Explanation:

hi

Answer 2

Given: Reaction of combustion of Ethane

$C_{2}H_{6} + 7O_{2} -->2CO_{2} + 3H_{2}O + heat$

To Find: Rate of reaction in terms of rate of disappearance of the reactants and the rate of formation of products.

Explanation:

Rate of reaction of any chemical process is the defined as the rate of disappearance of the reactants or the rate of appearance of the product over a period of time.

Rate of CO2 = $\frac{ [CO_{2}]^{2}]}{t}$

Rate of ethane= $-\frac{[ethane]}{t}$

Rate of oxygen =$-\frac{[O_{2}]^{7} }{t}$

In case of reactants, the rate is negative as reactants decrease over time. For products, the rate of reaction is positive because concentration increases over time.
