It's a reaction that does not depend on the amount of the reactant. For example, a saturated catalyst reaction, where the rate is limited by the number of open catalysts, is a zero order reaction because increasing the reactant won't do anything.

a zero order reaction graph of [A] v. time would turn out to be a negative slope linear line

A zero order reaction is independent of the concentration of reactants. It has a graph of [A] vs t that is a decreasing linear graph where the slope is -k.

We learned from lecture that a zero-order reaction can occur when a catalyst or enzyme is required. This catalyst or enzyme would be saturated and the reactant concentration would not affect the reaction rate. An example of a zero-order reaction is the reverse Haber process because the reaction rate is independent of the ammonia concentration.

A zero order reaction has a constant rate; it does not depend on concentration. When you plot concentration vs time for a 0 order reaction, the resultant graph should be a line with negative slope, and the slope = -k.

Professor mentioned that intermediate species and enzymes that help catalyze the reaction would be considered zero order since they have no bearing on the overall reaction.

Zero-order reactants mean that they do not depend on the amount of the reactants, only on the rate of k, which in this case would be a -k.

Zero-order reactions are typically found when a material that is required for the reaction to proceed, such as a surface or a catalyst, is saturated by the reactants. A reaction is zero-order if concentration data is plotted versus time and the result is a straight line.

Dr. Lavelle mentioned during his lecture that certain reactions involving enzymes can be zero order, as changing the concentration of the enzyme doesn't affect rate. This is because when the substrate is already fully saturated by the enzyme, further changing the concentration of the enzyme won't affect the reaction rate.

A zero order reaction would only depend on k for the rate since the concentration of the reactant would be raised to the power of 0, which is 1. And the graph would be [A] vs time.

A zero order reaction will not depend on on the concentration of the reactants. Its graph would show [A] vs t and would be a decreasing linear line.

The kind of reaction cannot be determined by just looking at the balanced equation, we can use a graph to tell. The zero order rate law occurs when a catalyst or enzyme is required. We can see through the rate reaction that it is limited by k, thus on a graph the zero reaction would be a straight line.

A zero order reaction graph of A concentration versus time would be a negative, linear line.

A zero order reaction is one where the concentration of the reactants does not affect the rate

A zero order reaction only depends on the rate constant and not the concentrations of reactants.

a zero order reaction is a reaction where it only depends on the rate constant rather than the concentrations of the reactants, since zero order means that there is a linear relationship between the concentration and time.

Zero order is independent of the concentrations of any of the reactants. This means the graph is always a negative line, -k. All it shows is [A] over time T.

Any reaction where rate doesn't depend on concentration.

Zero order means that even if you add more reactant, the rate will stay the same.

it means that we need no reactant, and we would have a 0 poewr exponent because the ratio of the two (if calculating this way) would be equal to one

It doesn't depend on reactant concentration. The graph of concentration vs. time is a negative linear line.

A zero order reaction is independent of the initial concentration, and is only dependent on the rate, k.

if a reaction is independent of the reactants, how would a catalyst affect the reaction? By allowing it to proceed with a lower activation energy?

In a situation where the concentration of the reactants does not matter, the order of the reaction would be zero.
