Write the equilibrium law expression for the following reaction: C(s) + O₂(g) = CO₂(g)

Given the following equation: NH4 (aq) + NO2 (aq) → N2(g) + 2H2O (1) AH = -122.4 kJ/mol How would decreasing the pressure effect the equilibrium? It would cause the equilibrium to shift to the right, favoring the products or the forward reaction. It would cause the equilibrium to shift to the left, favoring the reactants or the reverse reaction. It would not effect the equilibrium.

Consider the combustion of methane (as represented by the following equation). This is the reaction that occurs for a Bunsen burner, which is a source of heat for chemical reactions in the laboratory.

The equilibrium position is shifted to the left and the value for K decreases.

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 200. mL flask with 4.2 atm of methane gas and 2.8 atm of water vapor, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 2.5 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.
