Question

How to use an ice table and can you use some problems,analogies,and tips with ice table so i can fully understand it.

Answer 1

usually people choose change such way that calculation becomes easier,but right now to understand you take it as written you always do calculation of ICE table in terms of moles and then divide by total volume to get concentration of each product used in Kc equation

for example N2 +3H2 = 2NH3
here a =1,b=3 and c =2
at equilibrium if 1 mole of N2 is consumed then 3 moles of H2 must be consumed to form ammonia

this is where people get confused what is ax,bx or cx in the begining of ICE table

ax = 1 and bx = 3

here x(change) in a reactant A is N2 and 3x is of H2

if you still find difficulty comment i'll try to explain more
