Solution
The correct option is A yes It is possible to calculate the value of ΔH for the reaction H2(g)+Br2(l)⟶2HBr(g) from the bond enthalpy data as bromine is present in liquid state. The value of ΔH can be calculated from the bond enthalpy data only if all the reactants and products are present in gaseous state.
