## Zero Order Reactions

$\frac{d[R]}{dt}=-k; [R]=-kt + [R]_{0}; t_{\frac{1}{2}}=\frac{[R]_{0}}{2k}$

### Zero Order Reactions

What is the difference between zero, first, and second order reactions? What do they actually represent?

Lavelle did not specifically explain what the differences were between the order reactions other than the graphs of the outcome relative to the concentration of reactions. However the differences of order reactions gives insight to the reaction mechanism. The rate of the reactions depend on the reaction mechanism (number of steps to form products).

### Re: Zero Order Reactions

Different order reactions have different reaction mechanisms, or the number of steps to form the product.

### Re: Zero Order Reactions

Different order reactions have different numbers and sequences of steps to form the final product. They also have different powers in the rate law.

how do you know if it's zero order?

Do zero order reaction have to do with enzymes?

### Re: Zero Order Reactions

When deriving the zero order equation what happens to the negative in front of the k value?

### Re: Zero Order Reactions

Zero order reactions have a constant rate and are independent of any changes in concentrations.
