WebFor a first order reaction: ln ( [A]) = -kt + ln ( [A]0), the y variable is now ln ( [A]) and the x variable is still time. If we tried plotting ln ( [A]) versus time and get a straight line now, then it's first order. The slope will be -k and the y-intercept will be ln ( [A]0). WebA rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, …
