6.B Consider the chemical equation A(aq) + 3B(aq) 5 2C(aq) with an equilibrium
constant equal to 4.00 at a certain temperature. Each chemical is initially present
at a concentration of 0.25 molar.
(a) Set up a simple* expression for the equilibrium constant. (*freshman level)
(b) Determine whether the forward or reverse reaction is occurring.
(c) Set up an 1CE table to begin a calculation of the equilibrium composition.
(d) Without a better calculator or resources on the internet, you cannot solve for
the equilibrium composition. Which value for "x" works: 0.0261, 0.0315, or -
0.0129. If they all fail, then one of us did something wrong.
