A reaction was found to be third order in A. Increasing the concentration of A by a factor of 3 will cause the reaction rate to? increase by a factor of 27 increase by a factor of 9 triple decrease by a factor of the cube root of 3
The reaction A+B → products was found to have the rate law; rate = k[A][B]2. While holding the concentration of B constant, the concentration of A was increased from 0.010M to 0.030M. Predict by what factor the rate of reaction will increase. Select one: a. 9 b.3 c. No effect d. 16 e. 6
The reaction: A --> B + C is found by experiment to be zero order with respect to A. A graph of [A] vs time for the data has a slope of –5.0 x 10-2 M s-1. An experiment is run where the initial concentration of A is [A]0 = 1.0 x 10-3 M The integrated rate law can be expressed as: [A]0 – [A] = kt ln[A] – ln[A]0 = kt [A] = k t [A] / [A]0 =...

In a study of the decomposition of nitrosyl bromide at 10 °C NOBr—+NO+ Br2 the concentration of NOBr was followed as a function of time. It was found that a graph of 1/[NOBr] versus time in seconds gave a straight line with a slope of 1.27 m?s and a y-intercept of 3.98 M? Based on this plot, the reaction is order in NOBr and the rate constant for the reaction is M?? In a study of the decomposition of hydrogen...
The reaction A B + 2 C is known to be zero order in A and to have a rate constant of 3.0 x 10–1mol/L. An experiment was run at 25°C and initial concentration of reagent [A] = 2.0 x 10–3 M. What is the rate of the reaction? Unable to predict. The rate of the reaction is 3.0 x 10–1 mol/L. The rate of the reaction is 2.0 x 10–3 mol/L. The rate of the reaction is 6.0 x 10–4 mol/L.
