Question

ab,A2 , B2 are diatomic molecules if the bond enthalpies of a2,ab and b2 in the ratio 1:1:0.5 the enthalpy of formation of a bi from a 2 + b 2 is - 100 kj mol -1 what is the bond enthalpy of A2​

Answer 1

Answer:

Explanation:

A2+B2=2AB

1/2A2+1/2B2=AB

Deborah=-100kj

-100=(X/4+X/2)-x

X=400KJ/Mol
