How to determine the rate law of a reaction

WebThe rate law for a reaction can be determined by studying what happens to the initial instantaneous rate of reaction when we start with different initial concentrations of the reactants. To show how this is done, let's determine the rate law for the decomposition of hydrogen peroxide in the presence of the iodide ion. 2 H 2 O 2 (aq) 2 H 2 O ... Webof concentration in species B to determine the reaction order of B. We will perform two trials. In both trials we will hold the concentration of species D constant, and vary the concentration of species B in trial 1 and 2. For each trial we can now write a rate law: first trial: rate 1 = k[D] 1 x[B] 1 y Equation 4a xsecond trial: rate 2 = k[D ...

WebAnswer: 0.0195 mol/L. The integrated rate law for second-order reactions has the form of the equation of a straight line: 1 [ A] t = k t + 1 [ A] 0 y = m x + b. A plot of 1 [ A] t versus t for a second-order reaction is a straight line with a slope of k and a y -intercept of 1 [ A] 0. WebNow take values from experiment 2 and put them in rate equation. You obtain another eqaution like equation 1. Lets assume it equation 2. Divide equation 1 by 2 or 2 by 1 (whatever you like.) Solve it and you will easily get m (equals to 1). Now put the value of m in equation 2. You will obtain an equation with n and k as variables.
