Q4. A scientist was attempting to determine the frequency factor (A) of a reaction. From their...
An experimental plot of In(k) vs. 1/T is obtained in lab for a reaction. The slope of the best-fit line for the graph is -3880 K. What is the value of the activation energy for the reaction in kJ/mol? The reaction A + 2B + C Products has a rate law of Rate = k[A]][B]. By what factor would the reaction rate change if [B] is tripled? What is the rate for the second order reaction A - Products when...
The initial reaction rate for the elementary reaction A+2B-3C was measured as a function of temperature when the concentration of A was 2.5 M and the concentration of B was 1 M; the measurements are summarized in the table below. From these data, a) What is the activation energy? b) What is the frequency factor? c What is the rate constant as a function of temperature using T300K as the base case?
