When is Ksp determined for a system? at any time that the solid and liquid phases are both present
only after all solid has been dissolved
when equilibrium is established
when the two phase system is saturated

a chemical reaction happens

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042
