1.	Consider the following reaction between zinc and oxygen and choose the correctoptions out of the options given below :2 Zn (s) + O2 (g) → 2 ZnO (s) ; ∆H = – 693.8 kJ mol–1(i) The enthalpy of two moles of ZnO is less than the total enthalpy of twomoles of Zn and one mole of oxygen by 693.8 kJ.(ii) The enthalpy of two moles of ZnO is more than the total enthalpy of twomoles of Zn and one mole of oxygen by 693.8 kJ.(Explain between 1 and 2)
Answer» Consider the following reaction between zinc and oxygen and choose the correct options out of the options given below : 2 Zn (s) + O2 (g) → 2 ZnO (s) ; ∆H = – 693.8 kJ mol–1 (i) The enthalpy of two moles of ZnO is less than the total enthalpy of two moles of Zn and one mole of oxygen by 693.8 kJ. (ii) The enthalpy of two moles of ZnO is more than the total enthalpy of two moles of Zn and one mole of oxygen by 693.8 kJ. (Explain between 1 and 2)
