questions: 2,3 & 4

1. Consider the following reaction: PCI (1) + Cu(a) PCIS (s) + BBkJ Equilibrium will shift ? (or How wil this affect the amoun no change) of CI, ? increase, decrease.no Change change) Increase the temperature Backwand Increase Add a catalyst unchanged unchange Increase the amount of chlorine Forward Decrease Add more PCI Do change No Change Increase the volume Balk ward increase Increase the pressure Forward I fecrease 2. What is equal at equilibrium? 3. Consider the following reaction: N2(g) + O2(g) + 2NO(g) Which way will the equilibrium shift (if at all) when the following changes occur? a. Decrease the pressure b. Increase the pressure c. add more nitrogen d. add a catalyst e. add more NO f. remove some oxygen g. decrease the volume of the container Write out the equilibrium expression for the above reaction 4. Consider the following reaction: CH. (g) + H2O (9) + heat → CO(g) + 3 H2 (9) Which of the following changes will decrease the production of hydrogen? i. Lower the Temperature ii. Lower the pressure iii. Add more water 191

Answer 1

4. Lower the T, will decrease the production of H2 gas.
