3. For the reaction 103 (aq) + 51(aq) + 6H*(aq) → 312(aq) + 3H2O(1) the rate of disappearance of I (aq) at a particular time and concentration is 2.6 x 10-' mol/(L · s). What is the rate of appearance of 12(aq)? A) 4.3 10-' mol/(L •s) B) 7.8 x 10-3 mol/(L • s) C) -1.6 x 10 mol/(L • s) D) 1.6 x 10' mol/(L •s) E) 6.4 x 10^'mol/(L •s) 4. For the first-order reaction 1/2 N2O4(g) →...
Most of the time, the rate of a reaction depends on the concentration of the reactant. In the case of second-order reactions, the rate is proportional to the square of the concentration of the reactant. Select the image to explore the simulation, which will help you to understand how second-order reactions are identified by the nature of their plots. You can also observe the rate law for different reactions. In the simulation, you can select one of the three different...
1-The rate constant of a chemical reaction was measured at several temperature values and a plot of ln k (on the y-axis) was plotted against 1/T (on the x-axis, temperature was measured in Kelvin). If the slope of the plot was -9.21 x 103 K and the y-intercept was 13.0, what is the activation energy (EA) of the reaction in kJ mol-1? 2-In an enzyme-catalyzed reaction, the rate of the reaction depends on which of the following at very low...
