WebNov 6, 2015 · The question is asking for the rate constant, so all we have to do is find the gradient of this line and that will be equal to − k. m = [ A] 2 − [ A] 1 t 2 − t 1 = 7.00 × 10 − 2 M − 2.50 × 10 − 2 M 160 s − 345 s = − 2.43 × 10 − 4 M …
WebThe integrated rate law for the second-order reaction A → products is 1/ [A]_t = kt + 1/ [A]_0. Because this equation has the form y = mx + b, a plot of the inverse of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to k. Created by Jay. Sort by: WebFind the rate constant of this equation at a temperature of 300 K. Given, E a = 100 kJ.mol -1 = 100000 J.mol -1 A = 10 M -1 s -1, ln (A) = 2.3 (approx.) T = 300 K The value of the rate constant can be obtained from the logarithmic …
WebNov 13, 2014 · I find it a little weird that there's a 3 order of magnitude decrease in rate constant for a 50 K increase in temperature. Per the note below, the original equation I put had a mathematical error. The below should be correct: k 350 K k 300 K = exp { E a R ( 1 T 300 K − 1 T 350 K) } k 350 K k 300 K = exp { 103000 8.314 ( 1 300 − 1 350) } = 371.14
