Which of the following statements is false concerning the reaction of hydrogen gas and oxygen gas given below? H2(g) + 1/2 02(g) → H20(1); AH = - %3D 285.8 kJ O a. For the reaction H2(g) + 1/2 02(g) → H20(g), AH is not equal to 285.8 kJ. O b. The value -571.6 kJ pertains to 1 mol of liquid water. O c. Per mole of 02, the change in enthalpy is -571.6 kJ. o d. If the equation is multiplied by 2, AH becomes -571.6 kJ. e. If the equation is reversed, AH becomes +285.8 kJ.
