A gas is confined to a cylinder under constant atmospheric pressure, as illustrated in the following figure. When the gas undergoes a particular chemical reaction, it absorbs 829J of heat from its surroundings and has 0.69kJ of P-V work done on it by its surroundings. What is the value of ΔH for this process?

    From the first law of thermodynamics, we use the equation expressed as:

    ΔH = Q + W

    where Q is the heat absorbed of the system and W is the work done.

    We calculate as follows:

    ΔH = Q + W

    ΔH = 829 J + 690 J = 1519 J

    Hope this answers the question. Have a nice day.
