When the Al 3+ ion is hydrated, Al(H2O)63+ can act as a weak acid in water. Which of the following species could be produced in a reaction with water?      Al(H2O)63+( aq) + H2O( l) →?

A gas forms according to the following reaction:      H2(g) + ½S2( g)  H2S( g)        ΔH°rxn = –92 kJ The equilibrium constant  Kp  = 106 at 1023 K. Estimate the value of  Kp at 1418 K.

For water, an equilibrium is established as such:      H+( aq) + OH–( aq)  H2O( l) At 25°C, the concentration of H+ ions is 1.00 × 10 –7 mol/L. What would the value of the equilibrium constant be for water?

At high temperatures, carbon reacts with O 2 to produce CO as follows:      C( s) + O 2( g)  2CO( g). When 0.350 mol of O 2 and excess carbon were placed in a 5.00-L container and heated, the equilibrium concentration of CO was found to be 0.050  M. What is the equilibrium constant,  K c, for this reaction?
