T1/2 of second order reaction
WebAnswer: 0.0195 mol/L. The integrated rate law for second-order reactions has the form of the equation of a straight line: 1 [ A] t = k t + 1 [ A] 0 y = m x + b. A plot of 1 [ A] t versus t for a second-order reaction is a straight line with a slope of k and a y -intercept of 1 [ A] 0. WebFeb 12, 2024 · Since the reaction order is second, the formula for t1/2 = k-1 [A] o-1. This means that the half life of the reaction is 0.0259 seconds. 3 Convert the time (5 minutes) to seconds. This means the time is 300 seconds. Use the integrated rate law to find the final …
