Get started for freeThe formation of tetrafluoroethylene from its elements is highly exothermic:
(a)If a mixture ofgraphite, andis at equilibrium in a closed container, will the reaction go to the right or to the left ifis added?
(b) Rare bacteria from the planet Teflon eatand make Teflon for their cell walls. Will the reaction go to the right or to the left if these bacteria are added?
(c) Will the reaction go right or left if solid graphite is added? (Neglect any effect of increased pressure due to the decreased volume in the vessel when solid is added.)
(d) Will the reaction go right or left if the container is crushed to one-eighth of its original volume?
(e) Does the equilibrium constant become larger or smaller if the container is heated?
Use Le Châtelier’s principle and Kw in Table 6-1 to decide whether the autoprotolysis of water is endothermic or exothermic at 250C; (b)1000C; (c)3000C.
Althoughand CsOHhave little association between metal and hydroxide in aqueous solution,anddo form complexes with:

Prepare a table like the one in Exercise 6-B showing initial and final Concentrations of and (aq)insolution. Calculate the fraction of sodium in the form (aq)at equilibrium.
for dimethylamine is . Find for dimethyl ammonium ion.
For at 1362Kand is positive. A vessel is charged with , andat1362K.
(a) Will the reaction proceed to the left or the right to reach equilibrium?
(b) Calculate the pressure (Pa) of each species at equilibrium.
(c) If the mixture at equilibrium is compressed to half of its original volume, will the reaction proceed to the left or the right to re-establish equilibrium?
(d) If the mixture at equilibrium is heated from 1362 to 1407K , will HBr be formed or consumed in order to re-establish equilibrium?
