Find and fix each mistake in the equilibrium constant expressions. a. 2 H2S(g) ⇌ 2 H2(g) + S2(g) K = [H2][S2]/[H2S]

Hello everyone today. We are being asked to provide the K. Expression for the following reaction. So we have 10 oxide into a solid form. We have to carbon monoxide in the gas form and those two reactant. Give us one at 10 in a solid form. And to see otr carbon dioxide molecules in the gas form. An important thing to know for key expressions is that the only thing you include are gasses and Aquarius compounds. Therefore, whenever we see something in a solid form, we can immediately cross it out and know that we will not be including that in our K expression. The next thing you wanna do is write out K is equal to and we're going to write our products overreacting. So in brackets on the numerator, we're going to write our product which is C. 02 and notice that coefficient in front of that C. 02. That is going to be our exponent. So we're going to raise it to the power of two and our denominator, we're going to write C. O. In brackets. And that also has a coefficient and we're going to raise this C. O. To the power of two. This is our answer actually. So I hope this helped. And until next time
