WebThe rate law should be known, as the k value simply equals the slope of the selected graph, and the reaction order is given depending on which graph is linear 2. Rate = k [CV+]; input the [CV+] value into the equation and multiply by k to find the rate of the reaction at this point Students also viewed Exam 3 Practice Qs - Bio 2212 194 terms WebIn a chemical equation, a rate law connects the concentration of a reactant to the reaction rate. It's represented as rate = k [reactant1] [reactant2], with k being a reaction-specific rate constant. The reactant concentrations can be increased by an exponent (usually first or second power).
