Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from  an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

For the reaction

In this reaction gaseous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus is negative or less than zero.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
