1.	If standard enthalpy change Delta_(r )H^(Θ) + -2.05 xx 10^(3) kJ mol^(-1) calculate the energy of oxygen-oxygen bond in O_(2) molecules and compare the calculate value with the value given in the table.
Answer» Solution :`-205xx10^(3)=(694+3312+5x)=(4446+3712)` `4006+5x-8158=-4152+5x` `:. 5x=-2050+4152` `:. x=420.4` `DeltaH_(O=O)RARR 420.4 kJ mol^(-1)`
