Identify the correct set of statements (a) Heat of neutralisation of 0.3 mole HCl with 1 mole NaOH is -4.11 Kcal (b) for ( H ₂ O ) (liquid), ( H ₆ ) is more negative in comparison to the formation of ( H ₂ O ) (vapour) (c) Heat of combustion of ( H ₂( g ) ) is equal to heat of formation of ( H ₂ O ( l ) ) (d) Heat of hydrogenation is always endothermic in nature. Choose the correct answer from the options given below

Step-by-step solution

(a) Heat of neutralization of ( 0 . 3 ) mole HCl with 1 mole NaOH is ( - 4 . 1 1 ~ K c a l ) : The heat of neutralization for strong acids and bases (like HCl and NaOH) is typically around (-57.1 ~kJ / mol ) (approximately (-13.6 kcal / mol )). Thus, for 0.3 moles of HCl , it would be: Heat of neutralization (=0.3 -13.6 ) (b) For ( H ₂ O ) (liquid), ( Hf ) is more negative in comparison to the formation of H2O (vapour): This statement is correct because the enthalpy of formation for liquid water is indeed more nega
