# Does the following reaction show an increase or decrease in entropy? KCLO3(s) ---> 2KCL(s) + 3O2(g)

Entropy is associated with the degree of disorder, or number of degrees of freedom. In the reaction $2 K C l {O}_{3} \left(s\right) - \to 2 K C l \left(s\right) + 3 {O}_{2} \left(g\right)$ we see that 2 moles of a solid forms 2 moles of a solid and 3 moles of gas.
