← In the apparatus used to find the per cent of carbon, which substance absorbs the carbon dioxide?At high pressure, ammonia breaks down on a hot platinum surface by a zero order reaction: 2 NH₃(g) → N₂(g) + 3 H₂(g). A rigid vessel at a fixed temperature starts with pure ammonia at 0.800 bar. The graph shows the total pressure in the vessel against time: it rises in a straight line and reaches 1.040 bar after 120 s. In a second run at the same temperature, on the same surface, pure ammonia starts at 0.500 bar. Assume that the reaction stays zero order down to 0.250 bar of ammonia. What is the half-life of ammonia in the second run? →
