Assume each of the reactions below are at equilibrium. Determine which way the reaction would shift (toward the products, toward the reactants, or neither) if the reaction were stressed as indicated. Explain your answer to each one. Note that the \Delta H for each reaction is given. N2(g) + 3H2(g) ⇄ 2NH3(g) \Delta H = +22 kJ N2 is added H2 is removed Heat is added 2NO(g) + H2(g) ⇄ N2O(g) + H2O(g) \Delta H = +36 kJ NO is added H2 is removed N2O is added The system is cooled CO2(g) + H2(g) ⇄ CO(g) + H2O(g) \Delta H = -102 kJ CO is added Temperature is increased System is cooled CO2 is added H2 is removed

$\lim_{x \to \infty} \left( \frac{-6x^4 + 5x - 9}{-x^4 + 3x} \right) = 6$, use the graph below to find an integer value of $N$ that corresponds to $\epsilon = \frac{1}{4}$. Drag the movable black point to sample different integer values of $x$. You may pan and zoom in or out of the graph to explore the behavior of the function as $x \to \infty$.
