What temperature increase would be expected if the same 1.200 g sample of benzoic acid were combusted when the calorimeter contained 1.00 kg of water? Ccal(dry) = 2.39 kJ/°C qrxn = qeal = [Ccal,dry (AT) + Ccal,H2o(AT)] qcal = [Ccal,dry (AT) + (mH,0)(CH,0)(AT)] Combine like terms using AT. qrxn = -31.66 kJ %3D %3D %3D 31.66 kJ = [2.39 kJ/°C + (1.00 kg x 4.184 kJ/kg°C)](AT) %3D AT = [ ? ] °C %3D
