The rate constant for the reaction, . If the rate is , then the concn of (in mol/l) is
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.
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.
