The addition of solute particles into a solution causes: A. the solute particles to form seed crystals and make the solution freeze more easily.
B. the solvent particles to be attracted to the solute particles and to have less kinetic energy.
C. the solvent particles to be spread further out and have more to move, increasing their kinetic energy.
D. the solute particles to bump the solvent particles out of the solution, making it easier to boil.

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
