Review | Constants Periodic Table Leaming Goal: To understand reaction order and rate constants. For the general equation A+B+C+ dD. the rate law is expressed as follows: ratek AB" where mand n indicate the order of the reaction with respect to each reactant and must be determined experimentally and kis the rate constant, which is specific to each reaction Order For a particular reaction, aA +bB+CD the rate law was experimentally determined to be rate - KABC -- EBC2 A....
