Question

Keq for this reaction is 3.63.
A + 2B  C

The data in the table shows the concentrations of the reactants and product in two different
reaction mixtures at the same temperature. Does the data provide evidence that both reactions
are at equilibrium?
Concentrations of A, B and C
A (mol/L) B (mol/L) C (mol/L)
0.500 0.621 0.700
0.250 0.525 0.250

a.) No, the data give different Keq values
b.) No, the concentration of C is lower than B in the second mixture
c.) Yes the Keq remains constant
d.) Yes, there is always produ

Answer 1

product present*

Answer 2

c.) Yes the Keq remains constant
you need to calcuate Keq and you will see that it is the same in both cases:
Keq= C/(A*B^2) = 3,63
