Which of the following stament (s) is/are false ?A. `DeltaE=0` for combutins of `C_(2)H_(6)(g)` in a sealed rigid adiabatic containerB. `Delta_(f)H^(@) (S," monoclinic" )ne 0`C. If dissociation enegry `CH_(4)(g)` is `1656 KJ//"mole"` and `C_(2)H_(6)(g)` is `2812 kJ//"mole"`,then value of C-C bond energy will be `328 kJ//"mol"`.D. If `DeltaH_(f)(H_(2) O,g,) =- 242 kJ//mol `, `DeltaH_(vap)(H_(2)O,l)= 44kJ//mol` then `Delta_(f)H^(@)(OH^(-),aq)` will be be-142 kJ/mol |
