Question

We can predict the spontaneity of the reaction from free energy

change.

a) What you mean by a spontaneous process? Give an example.

b) The enthalpy and entropy changes of a reaction are 40.63 kJ

mol-1 and 108.8 JK-1 mol-1

respectively. Predict the feasibility or

spontaneity of the reaction at 27°C. ​

Answer 1

Answer:

the process which occurs without any external input ia known as spontaneous process

Answer 2

Ans) Gibbs equation helps us to predict the spontaneity of reaction on the basis of enthalpy and entropy values directly. When the reaction is exothermic, enthalpy of the system is negative making Gibbs free energy negative. Hence, we can say that all exothermic reactions are spontaneous.

a) A spontaneous process is one that occurs on its own, without any energy input from the outside. For example, a ball will roll down an incline; water will flow downhill; ice will melt into water; radioisotopes will decay; and iron will rust

b) Non-spontaneous

hope it's help uh!❤❤
