Question

The unit of rate constant of a zero order reaction
is :
(a) litre sec-1
(b) litre mol-1 sec-1
(c) mol litre sec-1
(d) mol sec-1
​

Answer 1

C) mol /lit sec-1

This can be obtained from the equation

aA + bB = cC + dD

Rate = K[A] ^x[B]^y

Where x+y = n is the order of the reaction

K = rate/K[A] ^x[B]^y

= concentration /lit/sec

I.e mol /lit sec-1
