Did entropy increase or decrease?
seropon [69]

Answer:

1) increase

2) increase

Explanation:

Entropy is the degree of disorderliness or randomness of a system. It is the measure of the unavailable energy in a system.

Entropy increases with increase in the number of particles. If the number of particles in a system increases from left to right, the entropy of the system increases accordingly.

In reaction 1, the number of particles from left to right increased from two to three hence the entropy was increased.

In reaction 2, the number of particles from left to right increased from three to five hence the entropy was increased.

What is the overall reaction order for this rate law: rate = k[A]2[B][C]?
dybincka [34]

Zero order are reactions in which concentration of reactant has NO effect on RATE OF REACTION.


2. First order are reactions in which concentration of one reactant is proportionate to the RATE OF REACTION.

Exp: That means when you increase the concentration of the one reactant, then the rate of reaction will increase by the same degree of extent.


3. Second order are reactions in which concentration of two reactant has an effect on the RATE OF REACTION.


Formula:

1. Zero order Rate = k

2. First order Rate = k(A)^m

3. Second order Rate = k(A)^m(B)^n


where () represents concentration

and equation is mA + nB -> Product.
