A zero-order reaction has a constant rate of 2.30*10-4 M/s. If after 80.0 seconds the concentration has dropped to 1.50*10-2 M, what was the initial concentration?

Initial concentration of the reactant = 3.34 * 10^ (-2) M

Explanation:

Rate of reaction = 2.30*10-4 M/s,

Time of reaction = 80s

Final concentration = 1.50*10-2 M

Initial concentration = Rate of reaction * Time of reaction + Final concentration

= 2.30*10-4 M/s * 80s + 1.50*10-2 M = 3.34 * 10^ (-2) M

Initial concentration = 3.34 * 10^ (-2) M
