Document Summary

[h+][ho-] = 1. 00 x 10-14 for weak acids in water: for weak based in water: ph = - log[h+] [h+] = 10-ph ph + poh = 14. [ho ]= k b " [base]init (the above weak acid/base equations assume <5% ionization and assume no alternative source of common ions) Kakb= 10-14 for a conjugate acid/base pair: which of the following is false about a system at equilibrium: 1: identify the correct equilibrium expression for the following reaction. 2: [a] [b]2 / [c] [d, [c] [d] / [a] [b]2, [a] [b]2 / [c, [c] / [a] [b]2, for the following reaction, determine whether the system is at equilibrium when [co] = 0. 50. M and [co2] = 0. 75 m. the system at equilibrium, because. C2h6 (g) + c2h4 (g: 0. 068, 0. 13, 14, 2. 2 x 10-5, what is the equilibrium concentration of n2o (g) (in moles/liter), if at equilibrium [n2]=
