WebZero-order reactions. The integrated rate law for the zero-order reaction A → products is [A]_t = -kt + [A]_0. Because this equation has the form y = mx + b, a plot of the concentration of A as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to -k. http://www.math.wsu.edu/idea/ChemKinetics/first_order.htm byomkesh web series download

WebOct 28, 2024 · The answer is (3) the reaction represented by the lower curve. I know that the reaction is first-order, hence r a t e = k [ A]. Thus, algebra reveals that [ A] = r a t e k. Thus, it makes sense that increasing the value of k means dividing rate by a larger number, yielding a smaller concentration at any given time. WebThe reaction orders in a rate law describe the mathematical dependence of the rate on reactant concentrations. Referring to the generic rate law above, the reaction is m order with respect to A and n order with respect to B. For example, if m = 1 and n = 2, the reaction is first order in A and second order in B. byomkesh web series
