Decreases
Explanation:
The molecules lose potential energy during chemical reactions.
In a chemical reactions, bonds are broken for new ones to be formed. The process of breaking and forming bonds diminishes the potential energy of a bond.
Potential energy is the energy at rest in a body.
In chemicals, potential energy is constituted by the chemical energy stored within the bonds.
When chemical reactions occur, the energy is released often in the form of heat energy. There is always a decrease in potential energy when chemicals reacts together.

<span>pepsin is an example of digestive enzyme that is released in the stomach and it breaks down food proteins to peptides.Trypsin is also one that hydoloyzes proteins into amino acids that the body can break down.</span>
You correctly said that you need the combined gas law.
combine gas law----> P1V1/T1= P2V2/T2
P1= ?
V1= 2.58 L
T1= 368K
P2= 777 torr
V2= 1.53 L
T2= 495K
Now we plug in the values.
(P1 X 2.58)/ 368= (777 X 1.53)/ 495 K
P1= 343 torr
