$x{H}_2$Oharr$1H_2+\frac{1}{2}{O}_2$

Selected Answer:

$K_p=\frac{1^1}{1^1\frac{1}{2^{\frac{1}{2}}}}(\frac{P}{N_{\text{t}\text{o}\text{t}}}{)}^{1-\frac{1}{2}-1}$

Answers:

$K_p=\frac{N_{H2O}^1}{N_{H2}^1{N}_{O2}^{\frac{1}{2}}}(\frac{P}{N_{\text{t}\text{o}\text{t}}}{)}^{1-\frac{1}{2}-1}$

$K_p=\frac{1^1}{1^1\frac{1}{2^{\frac{1}{2}}}}(\frac{P}{N_{\text{t}\text{o}\text{t}}}{)}^{1-\frac{1}{2}-1}$

$K_p=\frac{1^1\frac{1}{2^{\frac{1}{2}}}}{1^1}(\frac{P}{N_{\text{t}\text{o}\text{t}}}{)}^{1+\frac{1}{2}-1}$

$K_p=\frac{N_{H2}^1{N}_{O2}^{\frac{1}{2}}}{N_{H2O}^1}(\frac{P}{N_{\text{t}\text{o}\text{t}}}{)}^{1+\frac{1}{2}-1}$
