Ang- The first andere reaction is- 2N₂O(g) 2N, (q) + 22 (9) According to first onder kinetics - Rate constant, K = 2.303 log [A] initial concentration of 2018) [At] a concentration of NO at time t. When, to try them [A+] = [A] K-2 log2) 20.693 ..Now , k is given. The value at loook is 0.765? @ te (half-Life) of this reaction at 10ook will be ty2 by 2 0.693 Koook a 0.693 0.76 = 0.912 5

Now, At 1000k, rate constant, Koook = 0.765! At Book, note constant, KBook = 3.98x109 5'. Acconding to two point form of Abrhenius Equation - in hin) Fa (+-+z) a.

.
Where, ta = activation energy of this reaction. K₂ = Kloook = 0.765' - K8ook - 3.98x1045 T, - 800k & Tz - 1000K .: In co nco) - Gaia Cabo The In (1909.547) - Sega (0.00125-0-001) - Ea = In (1909.547) x 8.314 0.00028 = 251 236.486 J/mol 2 251-36 kJ/mol e. The activation enengy of this reaction 251-236 kg/mol N
