CO(g)+3H2(g)->CH4(g)+H2O(g)
The products becoming more ordered than the reactants
It increases
Synthesis reactions such as dehydration synthesis. For a reaction to proceed the there must be a net decrease in the Gibbs Free Energy of the system. The Gibbs Free Energy is made up of two terms: Enthalpy or Heat Content H Entropy S For a reaction in which the entropy is increasing to proceed there would have to be a sufficient release of heat content (enthalpy) such that Change in Free Energy G would be negative, ie decrease...
At high temperature the entropy increase.
water freezing
CO(g)+3H2(g)->CH4(g)+H2O(g)
2NO2(g) N2O4(g)
The meaning is more order.
The products becoming more spread out.
To decrease the entropy of a static body, you would need to decrease the disorder or randomness of its particles. This can be achieved by cooling the body, which can lower the thermal motion of its particles and reduce their entropy. Other methods include applying pressure to order the particles or removing impurities that contribute to disorder.
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.
For most reactions, the lowering of the temperature of the reactants.
