In the first-order reaction A→products, it is found that 99 % of the original amount of reactant A decomposes in 144 min .
Homework Answers
A° = 100
A(final) = 100-99 = 1
Time = 144 min
Ln( A°/A ) = rate constant * time
Ln(100/1) = rate constant * 144
Rate constant = 0.032
Half Life = 0.693 / rate constant
= 0.693 / 0.032
= 21.67 min
