ENTHALPY Flashcards
What can ENTHALPY for many cases be taken as?
The TOTAL energy change of system since any small difference is the work done
What mean when ENTHALPY =state function?
That E= depends only on initial and final enthalpy of system and not on any intermediate values arising from the reaction pathways
What is exoteric process??
ENTHALPY = less than 0 : process in which heat = transferred from SYSTEM to THE SURROUNDINGS
What is QUANTITATIVE MATERIAL, involved in change, proportional to??
The ENTHALPY change for a process
What is the heat capacity of material?
Amt of heat req to raise temp of material by 1 C
What does heat capacity show?
How much heat a material will absorb for certain temp change
How is enthalpy(H) of a system defined?
The change in ENTHALPY is heat transferred to/ from a system at constant pressure
