WebThe graph is a horizontal line The rate equation is rate = k Rate-concentration graph of a zero-order reaction In a first-order reaction, the rate is directly proportional to the concentration of a reactant The rate of the reaction increases as the concentration of the reactant increases WebThe integrated rate law for the second-order reaction A → products is 1/ [A]_t = kt + 1/ [A]_0. Because this equation has the form y = mx + b, a plot of the inverse 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. Created by Jay. Sort by: geraniol candle brands https://balverstrading.com
