Delta Changing Table
Combustion Reaction of solid benzoic acid?
A sample of solid benzoic acid (C6H5COOH) that weighs 0.800g is burned in an excess of oxygen to CO2(g) and H2O(l) in a constant-volume calorimeter at 25 degrees Celcius. The temperature rise is observed to be 2.15 degrees Celcius. The heat capacity of the calorimeter and its contents is known to be 9382J/degree Celcius
a. Write and balance the equation for the combustion of benzoic acid
b. Calculate the standard change in internal energy (delta U) in kJ/mol of C6H5COOH, for the combustion of benzoic acid above.
c. Calculate the standard enthalpy change (delta H) for the same reaction as in part (b).
d. Calculate delta H heat of formation for C6H5COOH, using the appropriate values from the bond energy table.
e. If 10.0 mol of CO2 are produced from the combustion of C6H5COOH, how much heat is produced?
c.
a) C6H5COOH + 15/2O2 ---> 7CO2 + 3H2O
b) Qv = Cv*dT = 9382J/°C * 2.15°C = 20171.3J
Mr(C6H5COOH) = 122g/mol => 0.800g / 122g/mol = 6.56*10^-3mol
20171.3J / 6.56*10^-3mol = 3076123.25J/mol
=> dU = 3076.12kJ/mol
c) Qp = Qv + pdV + VdP
V is costant => dH = dU + VdP
P = nRT/V => dP = dn*RT/V
==> Qp = Qv + dn*RT
dn = 7+3 - 15/2 = 2.5
R = 8.314 T = 298K
=> Qp = 20171.3J + 6193.93J = 26365.23J = 26.365kJ
dH = 26.365kJ / 6.56*10^-3mol = 4020.7kJ/mol
