WebA zero-order reaction is one in which the rate of the reaction is proportional to the 0th power of the reactant concentration. Consider the reaction: Where [A] 0 denotes the … WebIf you graph the first order reaction. The first order reaction basically ends up with a straight line with a positive slope. Then that's not right, because it has to be a negative slope. So it will have to be either zero first for second order, assuming that it's either zero, first or second. It has to be only one of these three.
