Chemistry Question on Chemical Kinetics
Which will be the unit of the rate constant for the reaction having rate K.[A]21[B]23?
A
Second-1
B
Mol/lit sec-1
C
Mol.lit sec-1
D
(Mol/lit)2.sec-1
E
Mol-1Lsec-1
Answer
Mol-1Lsec-1
Explanation
Solution
The correct answer is option (E): Mol-1Lsec-1
Rate=k[A]½[B]3/2
Rate = M/s =k [mol/L]½ [mol/L]3/2
On simplifying, k= (mol/L)-1/s k=Mol-1Lsec-1
