I have tried doing this so many times I cant get it ..please explain every step please thank you!!
I have set up my ICE table but I am stuck at the part where they give you the equilibrium concentration ahead of time, its messing up my calculations.
Q: Calculate the concentration of NO at equilibrium for the following reaction if the initial concentration of NO is 0.150 M and bromine is 0.100 M. The equilibrium concentration of bromine was determined to be 0.0352 M.
A. 0.020 M
B. 0.073 M
C. 0.065 M
D. 0.080 M
E. 0.115 M
Explanation / Answer
2NO(g ) + Br2(g) ? 2NOBr(g )
change in constration
-2x -x +2x
remaining conc
0.150-2x 0.100-x 2x
here
0.100-x=0.0352
x=0.0648
now eq conc of NO
0.150-2*0.0648
=0.0204
