4.41 g of propane gas (C3H8) is injected into a bomb calorimeter and ignited with excess oxygen, according to the reaction below

gayaneshka [121]

Answer : The heat of the reaction is -221.6 kJ

Explanation :

Heat released by the reaction = Heat absorbed by the calorimeter

$q_{rxn}=-q_{cal}$

$q_{cal}=c_{cal}\times \Delta T$

where,

$q_{rxn}$ = heat released by the reaction = ?

$q_{cal}$ = heat absorbed by the calorimeter

$c_{cal}$ = specific heat of calorimeter = $97.1kJ/^oC=97100J/^oC$

$\Delta T$ = change in temperature = $(T_{final}-T_{initial})=(27.282-25.000)=2.282^oC$

Now put all the given values in the above formula, we get:

$q_{cal}=(97100J/^oC)\times (2.282^oC)$

$q_{cal}=221582.2J=221.6kJ$

As, $q_{rxn}=-q_{cal}$

So, $q_{rxn}=-221.6kJ$

Thus, the heat of the reaction is -221.6 kJ

Balance each reaction and write its reaction quotient, Qc:(b) POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Komok [63]

When we balance the given equation

POCl₃(g) ⇄ PCl₃(g) + O₂(g)

We will get

2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

Solution:

Balancing the given equation

POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Balancing the number of O

2POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Balancing the number of P and Cl

2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

We get the balanced equation

2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

The reaction quotient will be

Qc = [product] / [reactant]

Qc = [PCl₃(g) + O₂(g)] / [POCl₃(g) ]
