Question

Which of the following statements is true? State functions do not depend on the path taken to arrive at a particular state. DErxn can be determined using constant volume calorimetry AHrxn can be determined using constant pressure calorimetry Energy is neither created nor destroyed, excluding nuclear reactions. All of the above are true.

Answer 1

as only depends on the state of 7 mars, pressure, density, entropy, etc. . All the above are true True statement: because state functions only depends on the the system , exampres are mass, pressure, density, one agauss. Ereaction means change in internal energy. Aeron. is always calculated at Constant volume whereas at means change in enthalpy of the reaction, which is measured at constant pressure. w is neither Energy consenation rule states that energy is ne created nor destroyed. In ease of nuclear reactions. Too the energy-mass Conservation is maintained. S Scanned with | Cand ther statements are all Corrector, true.
