The decompostion of N_(2)O into N_(2) and O_(2) in presence of Argon follows first order kinetics k=5.0xx10^(11)e^(-2000//T(K)). The activation energy is

Answer»

`16.628kJ"mol"^(-1)`
`166.28kJ"mol"^(-1)`
`166.28J"mol"^(-1)`
`16.628J"mol"^(-1)`

Solution :`K=(5xx10^(11)).E^((-200)/T),K=A.e^((-EA)/(RT)),(-2000)/T=(-Ea)/(RT)`
`epsilon_(a)=2000xxR=20000xx8.3.4=16.628,epsilon_(a)=16.628`KJ/mole
