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 s which is the answer.
I assume 1.0x10^-7 s = seconds.
