#### The rate constant for the reaction, . If the rate  is , then the concn of (in mol/l) is Option 1) 1.4 Option 2) 1.2 Option 3) 0.04 Option 4) 0.8

As we learned in concept

Order of a Reaction -

The order of a reaction is determined as the sum of the powers of the concentration terms that appear in the experimental rate equation. It is an experimental quantity.

- wherein

Formula:

Order has relation with stoichiometry & is determined experimentally. It can be zero/fraction/negative/positive

The reaction given is

Rate constant given is

According to the units of the rate constant , it is clear that the orderof the reaction is 1.

Rate given =

Since, the order of reactionis 1.
