The rate

Question

A particular chemical reaction looks like this A → B. A decomposes according to first order kinetics. The rate

constant is unknown. Through laboratory data it is determined that the time needed to reduce the concentration of A 50% (the half-life of A) is specified as: t1/2 = 60 min.

Part 1) Write the rate equation for the decomposition of A in terms of CA, time (t), and the rate constant (k)

Part 2) Determine the rate constant (k) in min-1

Part 3) What percentage of the reactant A is remaining after 15 minutes?
