Answer : The change in internal energy and change in enthalpy of the gas is 1143.2 J/mol and 1600.5 J/mol respectively.
Explanation :
(a) The formula used for change in internal energy of the gas is:
where,
= change in internal energy = ?
= heat capacity at constant volume =
= initial temperature =
= final temperature =
Now put all the given values in the above formula, we get:
The change in internal energy of the gas is 1143.2 J/mol.
(b) The formula used for change in enthalpy of the gas is:
where,
= change in enthalpy = ?
= heat capacity at constant pressure =
= initial temperature =
= final temperature =
Now put all the given values in the above formula, we get:
The change in enthalpy of the gas is 1600.5 J/mol.
Hello,
You balanced the equation and then you have to set up what is called a psychometric equation for each reactant so that you get the same unit for each in order to compare the two. so for (calcium hydroxide) = 78.5 g ÷ (40.1 + 32 + 2) = 1.0593 mol * Note: I just broke it down in my own science way..u can just get the molar mass of calcium hydroxide which is approx 74 g/mol
Hope this helps
