Find rate constant from first order graph
WebJan 30, 2024 · The integrated rate law for the first-order reaction A → products is ln [A]_t = -kt + ln [A]_0. Because this equation has the form y = mx + b, a plot of the natural log of … 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.

WebThe units of the rate constant, k, depend on the overall reaction order.The units of k for a zero-order reaction are M/s, the units of k for a first-order reaction are 1/s, and the units of k for a second-order reaction are 1/(M·s). Created by Yuki Jung. WebUsing the graph below, verify the reaction is first order, and calculate the rate constant. Problem 3: The decomposition reaction SO 2 Cl 2 (g) ---> SO 2 (g) + Cl 2 (g) is a first order reaction with rate constant k=2.2 x 10-5 sec-1 at 320C. What percent of SO 2 Cl 2 is decomposed at 320C after 90 minutes?
WebJun 9, 2015 · $\begingroup$ This standard exam question is a first order decay with half life (from the graph) of about 13 s. So the rate constant, k, is $(ln2)/t_{1/2}$, which is about $0.053 s^{-1}$. Hence the initial slope is -k times 0.4 M, giving $0.021 M s^{-1}$ as the magnitude of the initial slope.
