P_{gas}=K_{H}\times mole\;fraction\;of\;gas

           =K_{H}\times X_{gas}=K_{H}\left ( 1-X_{H_{2}O} \right )= K_{H}-K_{H}X_{H_{2}O}

                             P_{gas}=K_{H}-K_{H}X_{H_{2}O}

                                    y=mx+c

                                    m=-K_{H} =slope \; is \; negative
