Question

At a certain time in a reaction, substance A is disappearing at a rate of 1.0 x 10−2 M/s, substance B is disappearing at a rate of 2.0 x 10−2 Μ/s, and substance C is appearing at a rate of 6.0 x 10−2 M/s.

Select the correct stoichiometry of the reaction being studied.


1A + 2B → 6 C


4A → 2B + 3C


2A → B + 3C


A + 2B → 3C


A → 2B + 3C

Answer 1

The correct stoichiometry for the reaction being studied is

A + 2B = 6C

Step-by-step explanation:

Reactions involve the disappearance of reactants because it is being consumed and the appearance of products because it is being formed.

A and B are the reactants while C is the product of the reaction

The stoichiometric coefficient of A, B and C is obtained by dividing their rate by the smallest rate (1×10^-2 M/s)

Therefore, the correct stoichiometry is

A + 2B = 6C
