6. from the values of δh and δs, predict which of the following reactions would be spontaneous at 25ºc: reaction a: δh = 10.5 kj/mol, δs = 30 j/k ∙ mol reaction b: δh = 1.8 kj/mol, δs = –113 j/k ∙ mol if any of the above reactions is nonspontaneous at 25ºc, at what temperature might it become spontaneous? (16 points)

Both reaction A and reaction B are non spontaneous.

Explanation:

For a spontaneous reaction, change in gibbs free energy () should be negative.

We know, , where T is temperature in Kelvin scale.

Reaction A:

As is positive therefore the reaction is non-spontaneous.

If at a temperature T K , the reaction is spontaneous then-

or,

or,

or,

So at a temperature greater than 350 K, the reaction is spontaneous.

Reaction B:

As is positive therefore the reaction is non-spontaneous.

If at a temperature T K , the reaction is spontaneous then-

or,

or,

or,

So at a temperature greater than -16 K, the reaction is spontaneous.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
