In the reaction below,ΔH°_f is zero for ________. Ni (s)+ 2CO (g)+ 2PF₃ (g)→ Ni(CO)₂(PF₃)₂ (l) A)Ni (s) B)CO (g) C)PF₃ (g) D)Ni(CO)₂(PF₃)₂ (l) E)both CO (g)and PF₃ (g)

Question

Quizplus · Accepted Answer

The standard enthalpy of formation (ΔH°f) is zero for elements in their standard states. Nickel (Ni) in its solid form is in its standard state, so ΔH°f is zero for Ni (s).
