delta H vs q

[Dhwani Krishnan 1G]

What is the difference between and q? How are they related?

[katherinemurk 2B]

delta H is change in enthalpy and q is heat added to the system

[Harshita Talkad 4L]

Delta H is the change in enthalpy, while q is just heat, so it doesn't represent a change.

[Hadji Yono-Cruz 2L]

Delta H is the change in enthalpy and q represents heat.

[Alexandra Albers 1D]

In some cases, such as that of delta U, particularly in biological reactions, qp and delta H can be equal because the there is not work due to expansion, meaning that delta U=delta H.

[AngelaZ 1J]

Change in enthalpy (delta H) is the amount of heat (q) absorbed or released at constant pressure.

[Rami_Z_AbuQubo_2K]

When pressure is constant, q becomes q_p and this is equal to .

[George Ghaly 2L]

Delta H represent the heat that changed in reaction, while q represents the heat.

[MadelineHlobik]

How exactly do you solve for delta H?

[Kathryn 1F]

When pressure is constant, q becomes q_p and this is equal to .

Why is this? How does keeping the pressure constant equal to enthalpy? Thanks!
