The zero order means that the rate does not depend on concentration. Therefore the rate is constant even if the concentration changes. For each second it goes by 4.40 x 10^-4 is consumed

what about 45 second

=45 s x (4.4 x10^-4m/s) = 0.0198m

The total initial is therefore = 0.0198 + (1.50 x10^-2) = 0.0348m

A zero-order reaction has a constant rate of 4.40*10-4 m/s. if after 45.0 seconds the concentration has dropped to 1.50*10-2 m, what was the initial concentration? express your answer with the appropriate units.
