Follow-up Question

i think it is

The reaction quotient can be calculated from the reactants' and products' concentrations or partial pressures.

2 SmCl3(aq) + 6 Li(aq) → 2 Sm(s) + 6 LiCl(aq)

At non-standard conditions, the concentrations are:

[SmCl3] = 2.00 M

[Li] = 2.00M

[Sm] = 0 (solid)

[LiCl] = 0.0100 M

The reaction quotient (Q) can be calculated as follows:

Q = {[LiCl]^6}/[Sm3+ ]^2[Cl3]^2

= (0.0100)^6 /(2.00)^2 x (2.00)^2

= 6.25 x 10^-14
