Here's the solution to the question: a) The symbol "" in a chemical equation represents a reversible reaction or chemical equilibrium. b) A common fertiliser made from ammonia is ammonium nitrate or ammonium sulfate. c) Property: Transition elements can act as catalysts. Support: Iron, a transition element, is used as a catalyst in the Haber process to increase the rate of reaction without being consumed. d) i) An exothermic process releases energy. In the Haber process, the energy released during bond formation in ammonia molecules is greater than the energy absorbed to break bonds in nitrogen and hydrogen molecules. This net release of energy makes the process exothermic. ii) Increasing the temperature would increase the rate of reaction because reactant particles gain more kinetic energy, leading to more frequent and energetic collisions. However, since the forward reaction is exothermic, increasing the temperature would shift the equilibrium to the left, favoring the reactants and decreasing the yield of ammonia.
