For the general reaction aA + bB cC + DD, has the general rate law, rate k[A] [B].". What is the correct algebraic equation for determining the units of the rate constant, k, when concentration is in M and time is in seconds. O M M's k= k= MX+y.s M*+y O Ma+b O M:s k= k s MX+y O M o S k= k= Ma+b.s M O M*+y k= S
