    Look at using LaTex for formatting mathematics - there's a link in the resources on the forum page.

    Or post a photo of your working.

    What does the "*" represent?

    Is K a constant?

    K is a constant. You can treat P* as a constant too, but if you want to know P* stands for standard pressure in this case, A is degree of dissociation and P is total pressure.

    OK, but what about the first two points I raised.
