Forgive me I'm just a curious chemistry student. You can remember log(2), log(3), log(5) and log(7), which are roughly 0.7, 1.1, 1.6 and 1.95 This would allow you to calculate upto a reasonable accuracy For example log(6000) ≈ 3log(10) + log(2) + log(3) = 3*2.3 + 0.7 + 1.1 = 8.7 which is quite close to the real value at 8.6995... howell township middle school

"WebQ is used to determine whether or not the reaction is at an equilibrium. At any given point, the reaction may or may not be at equilibrium. By calculating Q (products/reactants), you can compare it to the K value (products/reactants AT EQUILIBRIUM) to see if the reaction is at equilibrium or not. If Q=K, the reaction is at equilibrium.
