energetic同rate既問題

enthalpy change of decomposition of nahco3
係:nahco3->1/2(na2co3)+1/2(co2)+1/2(h2o)
定係將上面果條成條*2?
因為我見到話
enthalpy change of decomposition of nahco3
係2nahco3->naco3+co2+h2o
但唔係應該以1mole黎計咩?
2nahco3->naco3+co2+h2o呢條係咪只係enthalpy change of reaction?
同埋rate equation度:
second order既:
-dA/A^2 = kdt
1/A = kt + C
呢步既左邊諗緊都唔明,請教教我-3-

yes, calculated as kJ/mol;
just integrate both sides.
