I was just wondering where you have notes on the Arrhenius equation because they weren’ t in the rate equations section and I wasn’ t sure where else they’ d be. For more information or corrections contact Tom Shattuck at twshattu. Kdswhu & khplfdo. 00385 s 900 s1 o [ A] e [ A] = − × − = 0.

When \ ( [ S] > > K_ m\ ), \ [ v = V_ { max} \ ] This means that the rate is equal to the maximum velocity and is independent of the substrate concentration. It is to be contrasted with thermodynamics, which deals with the direction in which a process occurs but in itself tells nothing about its rate. RATES OF REACTION MENU. Overall rates for forward reactions are shown as POSITIVE rates, therefore, all reactants ( which have negative rate of change) must have their rates negated d. 693 t kk = = 1 1 2 ln2 ln2 k 0.
