The relative rates of the reaction A + B S AB in vessels (1)–(3) are 4:4:1. Red spheres represent A molecules, and blue spheres represent B molecules. (1)-(3)

(a) What is the order of the reaction in A and B?

Video transcript

Hello. Everyone in this video, We're given three different vessels, vessel 12 and three. And they all have equal volumes. They all contain the reaction where X and Y yields Xy. So we can see here that the X molecules are represented by red spheres. And then the Y molecules are represented as Grace fears. And this question we're bringing asked to determine the order of direction in X and Y. So one thing that we can go ahead and assume is that the concentration is proportional to the number of molecules each vessel. So the first thing we'll do is to count each number of different molecules that we have in each vessel. So for vessel one we're gonna go ahead and count the red spheres or the X molecules first. So, we have to our X. And then we have four Y. Now for the second vessel here we have four X. And four Y. And then for vessel three we have four X. And to Y. All right. So, and vessels one and two. Let's put this in writing as well. The concentration of why remains the same. So, basically comparing vessels one and two here, that's what we're doing here. But the ex doubles. Which also means that the rate will also double before we can take away from this is that the reaction then is first order. And this is in regards to Y. R. X. So, this is whatever answers for this problem. Now, when we're comparing vessels two and 3, we can see that the concentration of X remains the same. And the concentration of why is halved, which means that the rate is also going to be had so we can take away from this, then, is that the reaction is also going to be first order in our molecule Y. So this right here, is going to be my last and final answer for this problem.
