Chemistry

Solid carbon can react with gaseous water to form carbonmonoxide gas and hydrogen gas. The equilibrium constant for thereaction at 700.0 K is Kp=1.60×10−3. If a 1.55-L reaction vesselinitially contains 247 torr of water at 700.0 K in contact withexcess solid carbon, find the percent by mass of hydrogen gas ofthe gaseous reaction mixture at equilibrium.
