    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
