For the reaction A to products}, the following data were obtained: t=0 s, A}]=0.715 M; 22 s, 0.605 M; 74 s, 0.345 M; 132 s, 0.055 M.
What is the half-life of the reaction?
To determine the half-life of the reaction, we need to find the time it takes for the concentration of the reactant to decrease by half.
Given the data:
t = 0 s, [A] = 0.715 M;
t = 22 s, [A] = 0.605 M;
t = 74 s, [A] = 0.345 M;
t = 132 s, [A] = 0.055 M.
We can see that the concentration of A decreases from 0.715 M to 0.605 M in 22 seconds. This means that it takes 22 seconds for the concentration of A to decrease by half.
Therefore, the half-life of the reaction is 22 seconds.
