Question
The endothermic decomposition of gaseous biofuel methanol (CH3OH) into hydrogen gas and carbon monoxide gas exhibits a concentration equilibrium constant of 2.111 at 250 C using nickel on silica catalyst. If the initial concentration of methanol 0.0041 moles per liter, what are the equilibrium concentrations of H2 gas and CO gas in a 1 pint container. Show work, including a balanced chemical equation, ICE table, equilibrium concentration constant expression, etc.! I can solve to the part where I get a cubic function of x (change in concentrations). However, I don't know where to go from there. I can't use any programs to solve cubic functions.Explanation / Answer
13. When healed, mercury(II) oxide, HgO, decomposes to form mercury and oxygen. Through this reaction, Joseph Priestley demonstrated the existence of oxygen in 1774. Write balanced equation for decomposition of mercury(II) oxide. 2HgO=2Hg+O2 14. Methanol, CH3 OH, decomposes to form carbon monoxide, CO, & hydrogen gas, H2. Write balanced equation for this decomposition reaction.
