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...
A student performed a chemical reaction which involved 3 reactants: A, B and C and measured the initial reaction rate but varied initial concentrations. The results showed that doubling the concentration of B doubled the reaction rate, doubling the concentration of C quadrupled the reaction rate and doubling the concentration of A had no effect on the rate of reaction. Find the overall reaction order and write the rate equation.
23) A chemical reaction of the general type: A → 2B is first-order, with a rate constant of 1.52 × 10-4 s-1. a. Calculate the half-life of A. b. Assuming the initial concentration of A is 0.067 mol L-1, calculate the time needed for the concentration to fall to 0.010 mol L-1.
