As a reaction proceeds, the ratio between the rate of consumption of reactant and the rate of formation of product:
wariber [46]

Answer:

Depends on the reaction.

Explanation:

Hello,

In this case, the answer is depends on the reaction since the ratios between the rates of both consumption and formation depend upon the stoichiometric coefficients in the chemical reaction. For instance, for the reaction:

A -> 2B

The relationship is:

\frac{1}{-1}r_A =\frac{1}{2} r_B

Therefore, we can see that the rate of consumption of A half the rate of formation of B, but is we consider the following chemical reaction:

2A -> B

The relationship is:

\frac{1}{-2}r_A =\frac{1}{1} r_B

Therefore we can see that the rate of consumption of A doubles the rate of consumption of B.

Best regards.
