Accepted Answer

Hello everyone today. We are being given the following reaction and asked to provide a K. C expression and also to determine if it is homogeneous or heterogeneous. When writing our case expression, we start with writing K. C. Is equal to the concentration of products and the numerator divided by the concentration of our reactant in the denominator. Something to note about Casey expressions is we don't include solids or liquids and with that we can get started. So our only product iodine chloride is going to be written in brackets here. And since that is the only product, we have to note that there's also that two in front of that compound. And so that coefficient to turns into an exponent for that compound. And then for our reactions on the denominator. The only one that we have is chloride gas which is c. L. two. And that goes in brackets as well. And so this would be our K. C expression. To determine if it is homogeneous or heterogeneous. We simply look at the states of matter for the reactant and products if they are the same, it is homogeneous if they are different heterogeneous. On the left here we have two reactions. We have a solid and a gas and on the right we have one product which equals just a gas. And so with that we see that our reactant and products are in different states of matter. And therefore this is considered a hetero genius reaction. I hope this helped until next time
