Question

At very low substrate concentrations, the reaction order of an enzyme-catalyzed reaction goes to this number. For 10 points each:
[10m] Give this number, which is the order of a chemical reaction in which the reactant concentration decreases exponentially over time, such as in radioactive decay.
ANSWER: 1 [accept first-order]
[10e] This quantity is uniquely a constant for first-order chemical reactions. It’s the time required for 50% of a substance, particularly a radioactive one like carbon-14, to decay.
ANSWER: half-life
[10h] The half-life of a first-order reaction equals this number divided by the rate constant. Give either an exact answer, or an answer accurate to three decimal places.
ANSWER: the natural logarithm of 2 [or ln(2); accept 0.693; prompt on log(2) or logarithm of 2; reject any partial answers]
