Taking into account definition of percent yield, the percent yield for the reaction is 76.25%.
<h3>Percent yield</h3>The percent yield is the ratio of the actual return to the theoretical return expressed as a percentage.
The percent yield is calculated as the experimental yield divided by the theoretical yield multiplied by 100%:
where the theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
<h3>Percent yield in this case</h3>In this case, you know:
- actual yield= 1.22 mol
- theorical yield= 1.60 mol
Replacing in the definition of percent yields:
Solving:
<u><em>percent yield= 76.25%</em></u>
Finally, the percent yield for the reaction is 76.25%.

Answer : The value of rate of reaction is
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The given chemical equation is:
Rate law expression for the reaction is:
As per question,
a = order with respect to = 2
b = order with respect to = 1
Thus, the rate law becomes:
Now, calculating the value of rate of reaction by using the rate law expression.
Given :
k = rate constant =
[NO] = concentration of NO =
= concentration of
=
Now put all the given values in the above expression, we get:
Hence, the value of rate of reaction is
