The images below show the process of a chemical reaction A B at various times. What is the half-life of the reaction at initial concentration? O=A=B t=0st=10st=20st=30st=40s In the reaction, A Products, a plot of 1/[A] vs. time is linear and the slope is equal to 0.056 M1s1. If the initial concentration of A is 0.80 M, how long will it take one-half of the initial amount of A to react? \begin{tabular}{l} 22s \\ 7.1s \\ \hline 0.045s \\ \hline 12s \end{tabular}
