Methane and water react to form carbon monoxide and hydrogen, like this: CH₂(g) + H₂O(g) → CO(g) + 3H₂(g) 2 Imagine 169. mmol of CH4 and 169. mmol of H₂O are added to an empty flask, and then answer the following questions. What is the rate of the forward reaction before any CH4 or H₂O has been added to the flask? What is the rate of the forward reaction just after the CH4 and H₂O has been added to the flask? What is the rate of the forward reaction at equilibrium? How much CH4 is in the flask at equilibrium? Zero. Greater than zero, but less than the rate of the reverse reaction. Greater than zero, and equal to the rate of the reverse reaction. Greater than zero, and greater than the rate of the reverse reaction. Zero. Greater than zero, but less than the rate of the reverse reaction. Greater than zero, and equal to the rate of the reverse reaction.

Study the reactions. I. N2 (g) + O2(g) → 2NO(g) II. CO(g) + 02(g) → 2CO2 (g) III. Na(s) + HCI(1) → 2NACI(aq) + H2(g) What factor would only affect the rate of the third reaction? the pressure of the reactants the temperature of the reactants the concentration of the reactants the surface area of the reactants

T = Chemical reactions produce one or more product substances from one or more reactant substances. If x molecules of reactant X combine with y molecules of reactant Y to produce z molecules of product Z, we write xX+yY→ ZZ. The reaction rater is the rate of change of concentration of 1 dz 1 dX one of the products over time; for this example, r = 1 dy z dt x dt dY dt dX dt Nitrogen gas N₂ and hydrogen gas H₂ combine to produce ammonia NH3 according to dY dX dt 1N₂ + 3H₂ → 2NH3.
