Formula to calculate the rate of reaction

WebDec 1, 2024 · Rate of reaction at a given time = gradient of the curve at that instant The rate of reaction at a given time, t, can be calculated through the following steps. Step 1: Draw a tangent (line AB) on the curve at the time … WebTo calculate k, we first need to convert the half-life, which is 2 hours, into seconds: 2 × 60 × 60 = 7200 s. We then simply substitute this value into the equation: k = ln ( 2) 7200 k = 9.6 × 10 − 5 s − 1. Remember that we found out the units of the rate constant for all first-order reactions earlier in the article.
