<u>Answer:</u> The amount of heat produced by the reaction is -21.36 kJ
<u>Explanation:</u>
Enthalpy change is defined as the difference in enthalpies of all the product and the reactants each multiplied with their respective number of moles.
The equation used to calculate enthalpy change is of a reaction is:
For the given chemical reaction:
The equation for the enthalpy change of the above reaction is:
We are given:
Putting values in above equation, we get:
To calculate the number of moles, we use ideal gas equation, which is:
where,
P = pressure of the gas = 1.00 bar
V = Volume of the gas = 2.67 L
n = number of moles of gas = ?
R = Gas constant =
T = temperature of the mixture =
Putting values in above equation, we get:
To calculate the heat released of the reaction, we use the equation:
where,
q = amount of heat released = ?
n = number of moles = 0.108 moles
= enthalpy change of the reaction = -197.8 kJ/mol
Putting values in above equation, we get:
Hence, the amount of heat produced by the reaction is -21.36 kJ
