All right, to figure out the relationship, if you think to yourself, So the rate increasedīy a factor of three. And what happened to the rate? The rate went from. So we've increased the concentration of A by a factor of three. We're going from aĬoncentration of A of one, to a concentration of A of three. Our first experiment with our third experiment now. And what happened to our rate? Our rate went from. So we've increased the concentration of A by a factor of two. We hold the concentration of B constant, and we observe the rate of our reaction to increase to. And our second experiment, we increase the concentration Of A is one molar, and the rate of our reaction, the initial rate of our reaction is. So in our first experiment, let's say the concentration And so we use the initial rate, where we have only reactants present, and no products. What the concentration, what effect the concentration And since reactions are reversible, if we have some products present, right, that can affect the rate of our reaction. Our reaction proceeds, the concentration of We change the concentration of A, and we see what effect that has So we're gonna hold theĬoncentration of B constant, so we hold the concentration of B constant in our experiments. So let's say we wanna figure out what the effect of theĬoncentration of A has on our rate of our reaction.
We can check this byĭoing some experiments. If you increase theĬoncentration of your reactants, you increase the rate of your reaction. The concentration of A and B, right, A and B would beĬloser together in space and more likely to react, therefore increasing the And the lower case a and the lower case b represent the coefficientsįor our balanced equation.

A reaction where A plus B gives us our products.
