Sec (3) Tutorial thermodynamic 1. It takes 330 joules of energy to raise the temperature of 24.6 g of benzene from 21.0°C to 28.7°C at constant pressure. What is the molar heat capacity of benzene at constant pressure? ----------------------------------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------- 2. Determine the amount of heat (in kJ) given off when 1.26 * 104 g of ammonia is produced according to the equation N2(g)+ 3H2(g) → 2NH3(g) ΔrH°= 5292.6 kJ mol−1 Assume the reaction takes place under standard-state conditions at 25°C. ----------------------------------------------------------------------------------------------------------------------------- 3. One mole of an ideal monatomic gas is initially at 300 K and a pressure of 15.0 atm expands to a final pressure of 1.00 atm. The expansion can occur via any one of four different paths: (a) Isothermal and reversible. (c) Adiabatic and reversible, (b) Isothermal and irreversible. (d) Adiabatic and irreversible. In irreversible processes, the expansion occurs against an external pressure of 1.00 atm. For each case, 𝟓 calculate the values of q, w, ΔU, and ΔH. {(monoatomic ideal gas) = , (1- } 𝟑  H.W. 3 Tutorial thermodynamics Name: ID Department Level 1. One mole of an ideal gas undergoes an isothermal expansion at 300 K from 1.00 atm to a final pressure while performing 200 J of expansion work. Calculate the final pressure of the gas if the external pressure is 0.20 atm. 2. Calculate the value of ΔH when the temperature of 1 mole of a monatomic gas increases from 25°C to 300°C. 3. Calculate the values of q, w, ΔU, and ΔH for the reversible adiabatic expansion of 1 mole of a monatomic ideal gas from 5.00 m3 to 25.0 m3. The temperature of the gas is initially 298 K.
