Cyclobutane decomposes to ethene in a first-order reaction. From measurements of the rate constant (k) at various absolute temperatures (T), the accompanying Arrhenius plot was obtained (ln k versus 1/T). 
a. Calculate the energy of activation, Ea.
b. Determine the value of the rate constant at 740. K. (In the plot, the units of k are s-1.)
Definitions:
Test-retest Reliability
Test-retest reliability measures the consistency of results when a test is repeated under identical conditions.
Standard Deviation
A statistic that measures the dispersion or variability of a set of data points from their mean, used in various fields to quantify the amount of variation.
Internal Consistency
A measure of the reliability of a test or scale, indicating how well the various items measure the same concept or construct.
Licensure Exam
A standardized test that individuals must pass in order to be legally recognized as a professional in certain fields.
