The temperature dependence of hemical reactions can be computed k = Ae ¼/RT, where k is the reaction rate (s¹), A is the frequency factor, E is the activation energy (J/mol), R is the gas constant [8.314 J/(mol K)], and T, is the absolute temperature (Kelvin, K). A compound has E= 1 x 10³ J/mol and 1=7 x 10¹6 s¹. the Arrhenius equation: Generate values of reaction rates for temperatures ranging from 273 to 353 degrees Kelvin in 1 degree increments. Save your reaction rates in a column vector. Be sure to use the period before the division operator to ensure the division in the exponent is carried out element-by-element through the vector of Ta values. Use the Arrhenius equation again to generate a second column vector of reaction rates for a second compound with activation energy E= 1.5 x 105 J/mol and frequency factor A = 8 x 10¹6 s¹¹. Use the subplot, plot and semilogy commands to generate a side-by-side plot showing the reaction rate dependence on temperature (k vs 7) for these two reactions. In the left subplot show the two reaction rate curves on standard axes. Use a logarithmic scale on the y-axis to show the same data on the right subplot. Be sure to title your figures, label the axes with units, and include a legend. Generate a third column vector that stores the ratio of reaction rates: k/k₂.
