Tin metal can be prepared by allowing solid tin (IV) oxide to react with hydrogen gas. Water vapour and solid tin are the products. [6 marks] a. Write out the balanced equilibrium equation. Make sure you include the states. b. The value of Key for this reaction is 1.04 at 500C. In an experiment, 1.200 moles of Sno, and 0.900 moles of H, are placed into a 3.00 litre container at 500C and allowed to react, forming an equilibrium. Calculate the [Hz] at equilibrium. Consider the following equilibrium reaction: Cs) + H2O(g) + CO(g) + H2(e) K=0.80 In an experiment, a student places 0.10 mole of C, 0.15 mole of H20, 0.25 mole of CO and 0.20 mole of Hinto a 1.0L flask. The student predicts that the [CO] will decrease as equilibrium becomes established. Is the student correct? Justify your answer. [3 marks]
