How to calculate rate constant for first order reaction?

WebFeb 12, 2024 · Write a rate law equation based on the chemical reaction above. This is the rate law: rate = k [ A] x [ B] y Next, the rate law equation from experiment 2 must be divided by the rate law equation for experiment 1. Notice that the [B] y term cancels out, leaving "x" as the unknown variable. Simple algebra reveals that x = 0. WebCalculating the rate constant is straightforward because we know that the slope of the plot of ln [A] versus t for a first-order reaction is − k. We can calculate the slope using any two points that lie on the line in the plot of ln [N 2 O 5] versus t. Using the points for t = 0 and 3000 s, Thus k = 4.820 × 10 −4 s −1. Exercise
