yuradex [85]

Answer:

Explanation:

Given parameters:

Volume of CO₂ = 24cm³

time taken for the reaction to complete = 8minutes.

Unknown:

rate of reaction

Soution

The reaction rate is a measure of speed of a chemical reaction. It is often calculated using the expression below:

Reaction rate = $\frac{change in concentration of reactant/product}{time taken}$

Reaction rate = $\frac{24}{8}$ = 3cm³/min

In this reaction, 3cm³ of carbon dioxide were produced per minute
