now knowing the connection between them. Let's take a look at the following example and try to answer the question. So in this question, it says for the following reaction to a solid plus three. B gas gives us to see gas. This equation has a Casey value off 4.9 times 10 to the negative nine at 25 degrees Celsius. Now we're saying which of the following statements is true, so I'm gonna take a look at the first one. It says the reaction is favored in the in the Ford direction. Remember, we've seen this type of terminology before. When is it favorite In the four directions? It's on Lee favorite in the four direction when K is greater than one. But we can see that based on the Casey, Value K is a lot smaller than one, so the four direction would not be favored. Next, we're gonna say the concentration of the products is greater than the concentration of the reactant. Again, this would Onley happen when K is greater than one. So this is also out. See, the reaction is favored in the reverse direction. This is true when K is less than one. And here are K. C is times 10 to the negative nine. So it's incredibly small, So the reverse direction is highly favored, so C is definitely true. Now let's take a look at the last one D. It says the value of KP will be larger than the value of K C. Now we know that the equation that connects them is k p equals K. C are tee to the Delta end. We know that, Casey, I told you, is 4.9 times 10 to the negative nine. Our is our gas constant, which doesn't change. Our temperature is 25 degrees Celsius. So we add 2 73 15 to that to get to 98. 15 Calvin when it's times to 98.15. Calvin, remember, we have to figure out what Delta and is here. So remember Delta and is gonna look at our e r products as gas. We have two moles of gasses products minus this Here is a solid. We don't look at solids. We're only looking at the gas minus three moles of gas so delta and is minus one. So when we punch that into our calculators we're gonna get back to 0.0 times 10 to the negative 10 and you can see that KP is actually smaller than Casey, So D is also false. Hopefully, guys were able to remember the relationship for our equilibrium. Constant its products overreact. INTs. When K is greater than one, the four direction is favored, and our products are greater in amount than react. It's when K is less than one than the reverse is favored, and our reactant will be greater than our products. Now that we've seen how to do this one, I want you guys to attempt to do this one on your own. So in this question, I want you to figure out what Casey is. I give you all the equilibrium amounts for each compound so we can use products overreacting to help us get to Casey. See if you guys can answer this, then come back and click on the explanation button and see what I do to solve the same exact question. Good luck, guys.
