Answer:
rA = 0.60 M/s
rC = 0.90 M/s
Explanation:
Let's consider the following reaction:
2 A+B ⇒ 3 C
The rate of each substance can be calculated like the change in its concentration divided by the change in time. Given the rate must always be positive, we add a minus sign before the reactants change in concentration.
The rate of the reaction is equal to the rate of each substance divided by its stoichiometric coefficient.
The rate of disappearance of B is 0.30 M/s.
The rate of disappearance of A is:
The rate of appearance of C is:
