Question

Atta Delta G in the process of melting of ice at minus 15 degree celsius is

Answer 1

Answer:

Delta G > 0

Explanation:

As delta H is positive and delta S is negative

From formula

∆G=∆H-T∆S

∆G must be positive

Answer 2

The Delta G  in the process of melting of ice at -15 degree Celcius is Positive.

• The Delta G is known as the symbol of spontaneity. It represents whether the reaction is going to be spontaneous i.e for the reaction to occur whether it requires any external force to be done on it, or it will proceed without any changes made.
• The spontaneous chemical reaction is represented by negative delta G.
• We are given with the reaction involving melting of ice at -15 degree Celcius.
• We know melting point of ice is 0 degree celcius, below which we will not get liquid water naturally.
• So, melting of ice at -15 degree celcius can't be a spontaneous reaction,as it needs to be done with changes in the pressure or other conditions.
• Therefore, the reaction is non spontaneous reaction, so the delta g is negative.
