JEE MAIN - Chemistry (2021 - 27th July Morning Shift - No. 3)
For a reaction of order n, the unit of the rate constant is :
mol1$$-$$n L1$$-$$n s
mol1$$-$$n L2n s$$-$$1
mol1$$-$$n Ln$$-$$1 s$$-$$1
mol1$$-$$n L1$$-$$n s$$-$$1
Explanation
Rate = k[A]n
comparing units
$${{(mol/l)} \over {\sec }} = k{\left( {{{mol} \over l}} \right)^n}$$
$$ \Rightarrow k = mo{l^{(l - n)}}{l^{(n - 1)}}{s^{ - 1}}$$
comparing units
$${{(mol/l)} \over {\sec }} = k{\left( {{{mol} \over l}} \right)^n}$$
$$ \Rightarrow k = mo{l^{(l - n)}}{l^{(n - 1)}}{s^{ - 1}}$$
