Enthalpy is a state function
state function
As stated before, a state function is a property whose value does not depend on the path taken to reach that specific function or value. In essence, if something is not a path function, it is probably a state function. ... Path functions are functions that depend on the path taken to reach that specific value .
. ... If there is no non-expansion work on the system and the pressure is still constant, then the change in enthalpy will equal the heat consumed or released by the system (q). ΔH=q. This relationship can help to determine whether a reaction is endothermic or exothermic.
Is Q same as Delta H?
Q is the energy transfer due to thermal reactions such as heating water, cooking, etc. anywhere where there is a heat transfer. You can say that Q (Heat) is energy in transit. Enthalpy (Delta H), on the other hand, is the state of the system, the total heat content.
How do you find Delta H from Q?
To calculate the enthalpy of solution (heat of solution) using experimental data:
Amount of energy released or absorbed is calculated. q = m × Cg × ΔT. q = amount of energy released or absorbed. ...
calculate moles of solute. n = m ÷ M. ...
Amount of energy (heat) released or absorbed per mole of solute is calculated. ΔHsoln = q ÷ n.
