The equation shows ATP hydrolysis at pH 7. Delta G degree for this reaction is 0

Question

The equation shows ATP hydrolysis at pH 7. Delta G degree for this reaction is 00.5 kJ/mol. Calculate Delta G degree (free energy change at sunward state) The standard-state free energy (Delta G degree) of hydrolysis for acetyl phosphoric is - 42.3 KJ/mol change for acetyl phosphate hydrolysis in a solution of Thermodynamics docs NOT: describe the flow and interchange of heat energy, an matter. allow the determination of whether a reaction spontaneous provide information on the rate of a reaction consider heat flow and entropy production consider the effect of concentration on net free energy change of a reaction. Living systems are: isolated systems that are totally contained open systems exchanging only energy with the surroundings. open systems exchanging both energy and nuttier with their surroundings e. none of the above. Which statement pertaining to the three basic systems is true? a- The internal energy of an isolated system is mostly conserved. Open systems can exchange matter with other open systems. Open systems can exchange matter with a closed system. The internal energy of an open system is always consent. A closed system can accept heat from an isolated system. Enthalpy change, Delta H, is: the sum of heat absorbed and work. not a thermodynamic state function. a measure of disorder in a system. determined by pressure change at a constant temperature. equal to the heat transferred at constant pressure and volume. All of them are true for the Second Law of Thermodynamics EXCEPT: Systems tend to proceed from ordered stales to disordered states. The entropy of the system plus surroundings is unchanged by reversible processes the entropy of the system plus surroundings increases for irreversible processes, all naturally occurring processes proceed toward equilibrium. None, all are true. Entropy change, AS, is the sum of heat absorbed and work. not a thermodynamic state function, c a measure of disorder in a system. determined by pressure change at a constant temperature. equal to the heat transferred at constant pressure and volume.

Explanation / Answer

Q1.

thermo will never provide information of the RATE of reation, since we only cover equilibrium

a, false, thermo actually studies this

b, via entropy and thermo law, this is correct

d, this is due to formulas of entropy and Q

e, this is studied in equilbirium of thermo

so choose C

Q2.

living systems are, by definition, an OPEN system, they can't be isolated since we need food form the universe

so

we also exchang heat via skin, choose D

Q3

a, true, since isoalted

b, is true, since it is the defintion

c, false, since closed system will not allow it

d, false, it could change

e, false, since it is isolated, will not flow heat
