So we can see that it took, this took 10 seconds for us to decrease the concentration Let's say that this is 10 seconds and 20 seconds and 30 seconds and 40 and so on. So we'd go over hereĪnd we find this point. So that would be right here on our graph. So, where would that be on our graph? Well this point right here Half of our reactant, obviously we'd be left with four.
We have eight particles we're starting out here. Our initial concentration here with eight dots. With some initial concentration, let me go ahead and change colors here, so we can think about it. Let's go back up here to our graph and let's think about half-life. And let's think about that for an example. Your half-life of a first order reaction is independent of the So here is your half-lifeįor a first order reaction. 693 divided by k, where k is our rate constant. To, let me rewrite this here, so our half-life, t 1/2, is equal to. So we have the negative of that, so we get a positive value Let's get out the calculatorĪnd let's find out what natural log of 1/2 is. So our half-life, t 1/2, would be equal to this would be negative natural log of 1/2 divided by k. So we're just solving for t 1/2, cause t 1/2 is our half-life. So now we have the natural log of 1/2 is equal to negative kt 1/2. So we can take the natural log of 1/2 this is equal to the natural log of e to the negative kt to the 1/2. So now we have 1/2 is equal to this is e to the negative kt 1/2.
And we can immediately cancel out our initial concentration of A. We're gonna find the half-lifeįor a first order reaction. And then this would be equal to the initial concentration of A times e to the negative k and then this would be the half life, so we plug in t 1/2 here. So on the left side we would have our initial concentration divided by two. So when the time isĮqual to the half-life, your concentration is half of In for our concentration and then the symbolįor half-life is t 1/2. So if the initial concentration, if this is the initial concentration here, what would be the concentration after half of it has reacted? We would get our initialĬoncentration divided by two. It's the time it takesįor the concentration of a reactant to decrease to half of its initial concentration. So over here is ourĭefinition of half-life.
So that's the idea of anĮxponential decay graph. So as you go out here, obviously your concentration of A is going to approach zero. And as time approaches infinity, as time goes to infinity, your concentration of A goes to zero. So our initial concentration is obviously this point right here, So you would have yourĬoncentration is equal to the initial concentration So when time is equal to zero, what is the concentration? So you would just plug in time Let's think about this point on our graph. So down here I've graphedĪn exponential decay graph, just to show you what it looks like here. Of A on the y-axis and we can put time on the x-axis. And now, it's a little bitĮasier to think about the graph. So we get that ourĬoncentration of A at time t is equal to the initial concentration of A times e to the negative kt. So we're gonna multiply both sides by the initial concentration of A. On the right side we haveĮ to the negative kt. We have our concentration over the initial concentration. So we're gonna take e to both sides here and that's gonna get So we're going to exponentiate both sides. And this is equal to negative kt, where k is your rate constant. That's the same thing as the natural log of the concentration of A over the initial concentration of A. So over here on the left, the natural log of the concentration of A at time t minus the natural log of the Going with the math here, so we eventually will If you're considering picking up a VR headset to play Half-Life: Alyx, check out the best VR headset deals right now.- Here we have one form of the integrated rate law forĪ first order reaction.
