The decomposition of [A] in solution at 80 °C proceeds via the following reaction:   A (aq) → B (aq) The dependence of the rate constant on temperature is studied and the graph below is prepared from the results. What is the energy of activation (kJ/mol) for this reaction?

Determine which of the two diagrams here (both for the same reaction) involves a catalyst, and identify the activation energy for the catalyzed reaction: 100 100 90 80 70 60 90 80 70 60 50 40 30 50 40 30 20 10 20 10 Extent of reaction Extent of reaction (a) (b) Energy (kJ) Energy (kJ)

A researcher raises the temperature from 47.4 to 64.7 °C and finds that the rate of the reaction doubles. What was the activation energy (in Joules) for this reaction? (R = 8.3145 J/molk)

A researcher raises the temperature from 39.4 to 56.2 o C and finds that the rate of the reaction doubles.  What was the activation energy (in J/mol) for this reaction? (R = 8.3145 J/mol K)
