Answer:
6.58 atm total
3.29 atm NO2
3.29 atm O2
Explanation:
Balanced equation:
O3 + NO → NO2 + O2
There are equal numbers of moles of both reactants, so neither is in excess and either could be considered the limiting reactant.
( 1.30 mol NO) x (1 mol NO2 / 1 mol NO) = 1.30 mol NO2
( 1.30 mol NO) x (1 mol O2 / 1 mol NO) = 1.30 mol O2
<em>Total pressure by using the formula;</em>
P = nRT / V
= ( 1.30 mol + 1.30 mol) x (0.08205746 L atm/K mol) x (401.0 K) / (13.0 L)
= 6.58 atm
<em>Partial pressure for NO2;</em>
(6.58 atm) x (1.30 mol NO2) / (1.30 mol + 1.30 mol)
= 3.29 atm NO2
<em>Partial pressure for O2</em>
6.58 atm total - 3.29 atm NO2
= 3.29 atm O2

Answer : 5100 KJ
Explanation : In the given reaction of
we can see that 2 moles of Al is producing -850 KJ of energy
so for 12 moles of Al we can calculate as;
12 moles of Al X
= -
5100 KJ
So, we can say that 12 moles of Al will need -5100 KJ of energy.
