Did you know?
WebHow do we determine the value of k for a given first-order reaction? The integrated first-order equation is the equation of a straight line. (Remember the general equation of a … WebFor a first order reaction, this is going to be the units for k, 1/time. For our second order reaction, second order rate law, I'm going to say rate, the exponents add up to 2. I'm going to make it simple on myself and rate equals k[A]². My rate again is Molarity over some unit of time equals K times Molarity, and this time Molarity is squared ...
