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

Marianna Evans · Answer 1

The correct stoichiometry for the reaction being studied is

A + 2B = 6C

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
