Calculate Delta G degree of this reaction at 37 degree C (human body temperature

Question

Calculate Delta G degree of this reaction at 37 degree C (human body temperature) arid 80 degree C (the temperature of some thermophilic bacteria). Assume Delta H degree' and Delta S degree' are independent of temperature. Label the following statements true or false: a. A reaction is said to be spontaneous when it can proceed in either the forward or reverse direction. b. A spontaneous process always happens very quickly. c. A nonspontaneous reaction will proceed spontaneously in the reverse direction. d. A spontaneous process can occur with a large decrease in entropy.

Explanation / Answer

3.

A. False:- all spontaneous reaction are irreversible so it can't proceed in both directions.

B. False:- spontaneity is thermodynamic property which determines feasibility not the rate of a chemical reaction as the rate is kinetic property.

C. True:- Spontaneous changes are irreversible so a process spontaneous in one direction would be non spontaneous in other and vice versa.

D. False:- spontaneous process occurs with an increase in entropy.
