What is the Equilibrium Constant for the Reaction Between PbCl2 and Ag+?

AI Thread Summary
The discussion centers on calculating the equilibrium constant (Kc) for the reaction between PbCl2 and Ag+. The provided Kc values for related reactions are Kc = 1.8*10^-10 for PbCl2 dissociation and Kc = 2.48*10^5 for Ag+ and Cl- forming AgCl. Participants express uncertainty about how to approach the calculation and emphasize the need to write the reaction equations and Kc formulas. The conversation highlights the importance of understanding the relationships between the reactions to derive the desired Kc value. Ultimately, the calculation is deemed solvable with the correct application of equilibrium principles.

Given the following reaction data at 25oC,
PbCl2  Pb+2 + 2Cl- Kc = 1.8*10-10
2Ag+ + 2Cl-  2AgCl Kc = 2.48*105
Calculate Kc for the reaction of PbCl2 and Ag+.
a. 7.2*10-16
b. 1.4*1015
c. 4.4*105
d. 4.5*10-5
e. can not solve

Is this solveable? I don't know where to start>?

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
