The question is :

For AgBr at 25C, with Ksp= 5.0E-13

For KNO3 solutions:

μ=0.050
γAg+ =0.8105
γBr- =0.8227

μ=0.0100
γAg+ =0.7565
γBr- =0.7794

μ=0.150
γAg+ =0.7199
γBr- =0.7529

μ=0.200
γAg+ =0.6914
γBr- =0.7340


Find the molar solubility of AgBr in 0.100-M potassium nitrate solution

what does these stand for?
γAg
γBr

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...
