Question

If a reaction experiences a large decrease in entropy and absorbs a large amount of heat, the reaction will be spontaneous.
True
False <--- my answer

Answer 1

Am I correct?

Answer 2

Decrease in entropy means that it's becoming more ordered.


Let's see how this affects our reaction.

delta G = delta H -Tdela S

If entropy change is negative then -(-t delta S will be positive.

Answer 3

If a reaction absorbs heat that means that it's Delta H is positive.

Answer 4

Putting this all together we have

Delta H positive
T delta S positive

Then this means delta G is positive

So yes you're right it's not spontaneous.

Answer 5

Thanks again :)

Answer 6

You see how I thought that through right?

Answer 7

Yes, I do, thanks
