Gas volume calculations

• What is the equation of an ideal gas equation

  pV=nRT

  p=pressure in Pa

  V=volume in m3

  T=temperature in kelvin

  n=number of moles

  R=gas constant=8.31Jk-1mol-1
• Explain why the bond enthalpy of C=O is greater than the bond enthalpy of C-O?

  1. C=O contains two electron pairs however C-O only contains one electron pair
  2. Therefore there’s a greater electron density between the positive nuclei in the C=O bond
