Determination of reaction rate

WebWe can write a generic rate law relating the reaction rate to the concentration of reactants: [ ] Rate = CV [ ]CV OH time ∆ = k x − z ∆ (2) The rate of the reaction is defined as the change in concentration of CV as a function of time, and x and z represent the order of the reaction with respect to the reactants. The values of x and WebFeb 20, 2024 · The ratio between the two right hand sides of the equation is 4, so after dividing the first equation by the second, you get: So y = 2. Next, you can find the order …
