Question

Qu

What can you determine about the feasibility of a
reaction if the enthalpy is positive and the entropy is
negative?

1
A. The reaction will usually occur because it is unlikely the
entropy will be greater than the enthalpy.
B. The Gibbs energy will always be positive, and the reaction will
never be feasible.
C. The Gibbs energy will always be negative, and the reaction will
always be feasible.
D. The reaction could be feasible above a certain temperature,

Answer 1

B. The Gibbs energy will always be positive, and the reaction will

never be feasible.

Step-by-step explanation:

The relationship between gibbs fee energy, G, enthalpy, H and Entropy, S is given as;

ΔG = ΔH - TΔS

If enthalpy is positive and entropy is negative, it means that we are going t always have a positive value for the gibbs free energy.

This means the correct option is option B.
