Web3 concentration of N 2, H 2, or NH 3.Say we monitor N 2, and obtain a rate of - d[N 2] dt = x mol dm-3 s-1. Since for every mole of N 2 that reacts, we lose three moles of H 2, if we had monitored H 2 instead of N 2 we would have obtained a rate - d[H 2] dt = 3x mol dm-3 s-1.Similarly, monitoring the concentration of NH 3 would yield a rate of 2x mol dm-3 s … WebWhat is activation energy in Arrhenius equation? Notice that when the Arrhenius equation is rearranged as above it is a linear equation with the form y = mx + b; y is ln(k), x is 1/T, and m is -E a /R. The activation energy for the reaction can be determined by finding the slope of the line. -E a /R = slope. E a = -R•slope.
