已知:强酸和强碱在稀溶液中发生反应时的中和热为-57.3 kJ ·mol-1,101 k Pa时辛烷的燃烧热为-5518 kJ· mol-1。则下列热化学方程式书写正确的是( )
A.H+ + OH-="=" H2O △H =-57.3 kJ · mol-1 |
B.2NaOH(aq)+ H2SO4(aq) ="=" Na2SO4(aq)+2 H2O(l) △H =-114.6 kJ·mol-1 |
C.2C8H18(l) + 25O2(g) ="=" 16CO2(g) + 18H2O(g) △H =-11036 kJ·mol-1 |
D.2C8H18(l) + 25O2(g) ="=" 16CO2(g))+18H2O(l) △H =-5518kJ·mol-1 |
