Pyetja

Reaksion endotermik, është:

A) $\mathrm{C_{(ng)} + O_{2(g)} \rightarrow CO_{2(g)}} \quad \Delta H 0$

B) $\mathrm{S_{(ng)} + O_{2(g)} \rightarrow SO_{2(g)}} \quad \Delta H 0$

C) $\mathrm{CaCO_{3(ng)} \rightarrow CaO_{(ng)} + CO_{2(g)}} \quad \Delta H > 0$

D) $\tfrac12\mathrm{N_{2(g)}} + \tfrac32\mathrm{H_{2(g)}} \rightarrow \tfrac{2}{2}\mathrm{NH_{3(g)}} \quad \Delta H 0$
