When 0.558g of biphenyl (C_12H_10) undergoes combustion in a bomb calorimeter, the temperature rises from 25.7^\circ C to 30.1^\circ C. Find DeltaE_rxn for the combustion of biphenyl in kJ/mol biphenyl. The heat capacity of the bomb calorimeter, determined in a separate experiment, is 5.86 kJ/{^\circ C}.

  • chemistry -

    q = Ccal x delta T
    dE/g biphenyl = q/0.5585 in kJ/g.
    dE in kJ/mol = kJ/g x molar mass biphenyl.
    Then c

  • chemistry -

    what is Ccal?

  • chemistry -

    calorimeter constant.
