The isomerization of cyclopropane follows first-order kinetics. The rate constant at 700 K is 6.20 x 10*(–4) min*(–1), and the half-life at 760 K is 29.0 min. Calculate the activation energy for this reaction. A) 5.07 kJ/mol D) 60. kJ/mol
B) 27.0 kJ/mol E) 270. kJ/mol
C) 50.7 kJ/mol

a. An experiment was conducted, the response variable is the connection of the chemical.

Explanation:

In this study, the chemical that is studied will have maybe different effects or concentrations in the different depths of the river. Is the variable that is expected to be shown.

The researches are going to manipulate the depth of the water that they are going to obtain the samples. This is the manipulate variable because they can modify if they want to obtain the sample at 1 m, 3 m or 5 m. the researches state the depth.

Hope this answer is useful
