Print Periodic Table Ebook Question 11 of 18 (1 point) X Incorrect X In The rate constant for the reaction of nitrogen with oxygen was determined at four temperatures. Calculate the activation energy and frequency factor A for the reaction given the data below. N, (g) o g) 2 NO (g) T (K) k (cm /molecule s) Number 250 7.18 x 10-8 14.2 kJ mol 275 1.36 x 10-7 300 2.31 x 10-7 325 3.46 x 10-7 Number cm molecule s 7.2 x 10 s Analyze The Arrhenius equation is: In (k) In (A) R T C Try Again Q View Solution 9 10 11 Progress 12 13 14 15 16 17 18 -D Exit Activity

Explanation / Answer

ln k = - Ea / RT + ln (A)

ln (7.18 x 10^-8) = - 14.2 / (8.314 x 10^-3x 250) + ln A

A = 6.66 x 10^-5
