Chemistry Graphs: Arrhenius Plot

 
The rate constant, k, for a given reaction changes with temperature. The plot of ln k versus 1/T gives a linear plot with a negative slope. Ea represents the activation energy for the reaction, in KJ/mole. R is the ideal gas law constant, 8.314 J/mole K. Temperature is measured in Kelvin.
 
The equation of the line for the graph is:
 
 

General Questions


If the slope of the line is -1.10 x 103 K, what is the activation energy for the reaction?
1. 





If ln k = -7.1, what is the value of k?
2. 





Will the rate constant, k, increase or decrease as the temperature increases?
3. 





What is the unit for the variable being plotted on the x-axis?
4. 





Simplify the following expression: ln k1 - ln k2
5.
