Arrhenius equation is
k = AeEa/RT
k = Ae-Ea/RT
k = AeRT/Ea
k = Ae-RT/Ea
If we plot log k Vs 1/T, by Arrhenius equation, the slope is
-Ea/R
+Ea/R
-Ea/2.303R
+Ea/2.303R

reacting with products
If the rate of the reaction is equal to the rate constant, then the order of the reaction is
3
0
1
2
The time of half change of a first order reaction is _______initial concentration.

The rate law of the reaction 2N2O5 → 2NO2 + O2 is
r = k[N2O5 ]
r = k[N2O5 ]2
r = k[N2O5 ]0
r = k[NO2]4 [O2]
