Question

For the reaction H2O) =H% + OH", if x moles of H and y moles of OH are formed K. is y A. *?/(1 – x) C. 1/xy D. xy ​

Answer 1

Answer: Correct option is B)

The standard enthalpy change of formation of a compound is the enthalpy change which occurs when one mole of the compound is formed from its elements under standard conditions. The equation showing the standard enthalpy change of formation of water is

H

​ O

2

​ (g)⟶H

2 ↑

​ O(l) 1 mole of water formed.

∴ Enthalpy of formation is −X2kJ/mol.
