Iodine combines to form I2 in liquid propane solvent with a constant of 1,5 x 10^10 L/mol. The rate is 2nd order. Since the reaction occurs quickly, a flash of light creates an I concentration of .0100M. How long will it take for 95% of the atoms to form I2?

This must use a second order rate equation, but I cannot get 1.0x10^-7 which is the answer

  • chemistry -

    1.0 x 10^-7 WHAT?

  • chemistry -

    Sorry it is 1.0x10^10 seconds.
    Any idea how to obtain this answer?
