Question

If for a reaction ΔH is negative and ΔS is posetive then reaction is (a) spontaneous at all temperatures (b) nonspontaneous at all temperatures (c) spontaneous only at high temperatures (d) spontaneous only at low remperatures

Answer 1

Answer:

explain with a story from gandhi life on why he wanted to fight for the Indians??? coming of gandhi

Answer 2

Answer:

Option (a) is correct.

Explanation:

Since we know that the Gib's free energy for the reaction is given by

$\Delta G^{0} = \Delta H -T\Delta S$

For the reaction to be spontaneous the Gib's free energy must be negative.

It is already given that ΔH is negative and ΔS is positive,So for getting the Gib's Free energy negative "all temperature above zero degree Celsius is valid".

So, option (a) is correct.
