please respond to both ill give a good review

The second-order reaction 2 Mn(CO) -- Mn,Cho has a rate constant equal to 3.0 X 10'M's at 25C, the initial concertiration of Mnico) 83.0 x 10M, how long will it tako for 90.5 of the reactant to disappear? O 1.1x10. O 10 X 108 1,0 10-15 O 9.0x10 Constants Periodic Table Part A For the reaction 2A + BC, the initial rate is measured at several different reactant concentrations.
