Accepted Answer

Hello everyone today. We are being asked to provide the K. Expression for the following reaction. So we have four moles of copper oxide in the solid form. We have methane in the gas form and those to come together to produce CO two in the gas form, Copper in the solid form and two H 20 molecules in the gas form. An important thing to know for K expressions is that you only include compounds in a gas form or in an acquis form. Therefore when you see any substance in a solid form or a liquid form you can immediately cross it out. So we just crossed out those two there. The next thing you want to do is write K. And we're gonna draw this fraction line and we're gonna have our products overreact ints. And so we want to do the first product that we can write in the numerator. We're going to put it in brackets is C. 02. It doesn't have any coefficients. So there's no exponent needed. The next product that we can write is water. So we're gonna right next to it another bracket H 20. And since there is a coefficient of two we're going to write an exponent of two for the water. Now we can focus on the reactant and we only have one methane. So we're gonna write in brackets. Ch four and this is our answer. I hope this helped and until next time
