Determination of reaction rate

WebTools. In chemical kinetics, the overall rate of a reaction is often approximately determined by the slowest step, known as the rate-determining step ( RDS or RD-step [1] or r/d step … 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
