    Hello everyone!
    I study AQA chemistry and at A2 level. In the topic of thermodynamics in unit 5, questions regarding data book values come up a lot.

    My question is what are data book values? Are they like theoretical values?

    Also why do ionic compounds not have data book values? Is there a specific reason?

    Data book values are like values that can be looked up, on google for example. It's like we have data book values for mean bond enthalpies, they're averages and can be looked up :s don't worry about them, they are just reference points. In exam they may say why is your calculation less than data book value, well maybe cause of heat loss in combustion, or you have used average values, etc..
