a. Order of a reaction: It is the sum of the power to which the concentration terms are raised in the rate law equation. It can be 0,1 or 2
Molecularity is the minimum no. of molecules taking part in a chemical reaction.
Order of reaction is applicable for complex reaction but molecularity has no meaning for the complex reaction.
b. Given: T1/2= 25 minutes
For 1st order reaction, T1/2=
k = = 0.0277 min-1
now, as 80% reaction is complete, so amount left [R] =100-80 = 20
T= 58.113 minutes
a. k1= 2.5 × 104 s-1 T1= 270C = 300K
k2= 7.5 × 104 s-1 T2= ?
Ea= 19.147 × 103 J/mol
We know that
b. A bimolecular reaction is kinetically first order when one of the reactants is in excess.
CH3COOCH3 + H2O (excess) → CH3COOH + CH3OH
