Question

For rubber-like polymers, an equation may be written for the Helmholtz energy change in the polymer when it is stretched a length dI against a force F dA = F dl - S dT The Maxwell relation derived from this expression is (partial differential F/partial differential t)_T = (partial differential S/partial differential T)_t (partial differential l/partial differential S)_t = (partial differential T/partial differential F)_s (partial differential F/partial differential T)_t = (partial differential S/partial differential l)_T (partial differential l/partial differential F)_T = -(partial differential T/partial differential S)_F (partial differential F/partial differential S)_T = -(partial differential l/partial differential T)_S A reaction is definitely spontaneous if: delta G is a negative value Both enthalpy and entropy increase delta H is negative and delta S is positive Both enthalpy and entropy decrease delta H is positive and delta S is negative I and III I and II II and V III and IV cannot be determined without temperature

Explanation / Answer

Q.No-2

Correct answers are

Reaction will be spontaneous if delta G value is negative.

We know the relationship delta G = delta H - T delta S

Delta G will be negative if delta H value is negative and delta S value is positive.

In option , I came two times so I cannot tell.You can check and choose what I said above.
