according to reaction 3 moles no are reacting with 1 mol of [tex]o_3[/tex] ,then 0.49 mol of no will react with [tex]\frac{1}{3}\times 0.49[/tex] moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and [tex]o_3[/tex] is an excessive reagent.
enthalpy change for the reaction between the given volumes of the gases is :
[tex]\delta h_{reaction}\times \text{moles of no}=-311.85kj/mol\times 0.49 mol=-152.80kj/mol[/tex]
Hi there! Hopefully This answer will answer your question! If you have any questions about my answer let me know!
Explanation:
Pond Succession. A geological event, such as a glacier or sink hole, can create a pond. ... Yet, if left alone, ponds will fill in with dirt and debris until they become land. It often takes hundreds of years for a pond to be transformed from a body of clear water into soil.
answer: the value of enthalpy change will be -152.80 kj.
solution:
pressure = 1atm , temperature = [tex]25^oc[/tex]= 298 k [tex])0^oc=273kelvins[/tex]
[tex]o_3+3no\rightarrow 3no_2,\delta h_{reaction}=? [/)
[tex]\delta h_{no}=90.4kj/mol[/tex]
[tex]\delta h_{no_2}=33.85kj/mol[/tex]
[tex]\delta h_{o_3}=142.2kj/mol[/tex]
[tex]\delta h_{reaction}=\sum \delta h_{products}-\sum\delta h_{reactants}=3\times\delta h_{no_2}-(3\times \delta h_{no}+\delta h_{o_3})[/tex]
[tex]\delta h_{reaction}=33.85-(90.4+142.2)=-311.85kj/mol[/tex]
given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.
[tex]v_{no}=12.00 l,v_{o_3}=8.50 l[/tex]
[tex]pv_{no}=n_{no}rt=1atm \times 12.00 l=n_{no}\times 0.0821 atml/k mol \times 298 k[/tex]
[tex]n_{no}=0.49 moles[/tex]
[tex]pv_{o_3}=n_{o_3}rt=1atm \times 8.50 l=n_{o_3}\times 0.0821 atml/k mol \times 298 k[/tex]
[tex]n_{o_3}=0.34 moles[/tex]
according to reaction 3 moles no are reacting with 1 mol of [tex]o_3[/tex] ,then 0.49 mol of no will react with [tex]\frac{1}{3}\times 0.49[/tex] moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and [tex]o_3[/tex] is an excessive reagent.
enthalpy change for the reaction between the given volumes of the gases is :
[tex]\delta h_{reaction}\times \text{moles of no}=-311.85kj/mol\times 0.49 mol=-152.80kj/mol[/tex]
