causes an excess of CI- in the reaction and in order to relieve itself from increase of \( \mathrm{CI}_{-} \), the reaction will shift towards to the right. 2. a) How can the reaction rate be increased? b) What conditions would result in a high yield? c) In NH3 production, the yield is increased by condensing the \( \mathrm{NH} 3 \) to a liquid and removing it. Would condensing ethanol have the same effect? (d) Where will equilibrium shift if you increase the temperature? 3.

Consider $4 \mathrm{NH}_{3}(g)+5 \mathrm{O}_{2}(g) \rightleftharpoons 4 \mathrm{NO}(g)+6 \mathrm{H}_{2} \mathrm{O}(g),$ $\Delta H=-904.4 \mathrm{~kJ} .$ How does each of the following changes affect the yield of $\mathrm{NO}$ at equilibrium? Answer increase, decrease, or no change: (a) increase $\left[\mathrm{NH}_{3}\right] ;(\mathbf{b})$ increase $\left[\mathrm{H}_{2} \mathrm{O}\right] ;(\mathrm{c})$ decrease $\left[\mathrm{O}_{2}\right]$ (d) decrease the volume of the container in which the reaction occurs; (e) add a catalyst; (f) increase temperature.

How does each of the following changes affect the yield of $\mathrm{NO}$ at equilibriun?? Answer increase, decrease, or no change: (a) increase [NII $\left._{3}\right]$; (b) increase $\left[\mathrm{H}_{2} \mathrm{O}\right]$; (c) decrease $\left[\mathrm{O}_{2}\right] ;$ (d) decrease the volume of the container in which the reaction occurs; $(e)$ add a catalyst; (f) increase temperature.
This reaction is endothermic. $$ \mathrm{NH}_{4} \mathrm{Cl}(s)+\mathrm{H}_{2} \mathrm{O}(l) \rightleftharpoons \mathrm{NH}_{4}{ }^{+}(a q)+\mathrm{Cl}^{-}(a q) $$ Predict the effect (shift right, shift left, or no effect) of these changes. (a) increasing the reaction temperature (b) decreasing the reaction temperature
