Question

From the data below for the reaction B + CD Find the values of the pre-exponential constant (A), activation energy (E), and the reaction orders a and y for a rate expression with the form: Rate = kPPS Here k = Aexp(-5). Report a and y to one significant figure. Include any plots or analysis you use to develop the expression. Assume conversion is less than 2% for all measured rates.
