1. 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

2.

A + 3B → 2C

If ∆B/∆t is −0.547 M/s, what is ∆A/∆t in M/s?

Be mindful of the sign for change in product and change in reactant concentration.
