A35.6 g sample of ethanol (c2h5oh) is burned in a bomb calorimeter, according to the following reaction. if the temperature rose from 35.0 to 76.0°c and the heat capacity of the calorimeter is
23.3 kj/°c, what is the value of dh°rxn? the molar mass of ethanol is 46.07 g/mol.
c2h5oh(l) + o2(g) → co2(g) + h2o(g) δh°rxn = ? (points : 1)
(a) -1.24 × 103 kj/mol
(b) +1.24 × 103 kj/mol
(c) -8.09 × 103 kj/mol
(d) -9.55 × 103 kj/mol
(e) +9.55 × 103 kj/mol
