Question

. What is meant by entropy driven reaction? How can a reaction with positive changes of enthalpy and entropy be made entropy driven?

Answer 1

\[\Delta G = \Delta H +T \Delta S\]

criteria for a spontaneous reaction, is that delta G = negative

sp let's say the the H = y, and S = x

The temperature won't be negative (Kelvin) so the product from T and S is z, a positive number

so if y<z

e.g. delta G = 4 - 7 = -3

then delta G = negative number, which satisfies the criteria for spontaneity.
