of will remain after 7.0 min.
Further Explanation:
Order of reaction:
This determines dependence of rate on power of concentration of reactants involved in any chemical reaction.Reaction can be of first order, second-order, and third-order and so on.
A reaction is said to be first-order reaction if its rate varies directly with the concentration of reactants.
The first-order decomposition of occurs as follows:
Since decomposes to form and through first-order reaction, its rate constant can be determined with the help of below mentioned formula.
The expression to calculate rate constant for first-order reaction is as follows:
…… (1)
Here,
<em>k</em> is rate constant.
<em>t</em> is the time.
isinitial concentration of reactant.
isconcentration of reactant at time t.
The initial concentration can be calculated as follows:
The value of <em>t</em> is 7.0 min.
The value of is 0.0119 M.
The value of kis .
Substitute 7.0 min for <em>t</em>, 0.0119 M for and for <em>k</em> in equation (1) to calculate for decomposition of .
Solving for ,
Therefore 0.0006789 moles of will remain after 7.0 minutes.
