Equilibrium constant and concentrations of HI, H2 and I2

AI Thread Summary
At 350 degrees Celsius, the equilibrium constant for the reaction involving HI, H2, and I2 is 70. The equilibrium concentrations are given as 1.32 mol/L for HI and 0.100 mol/L for H2. To find the concentration of I2, the equilibrium expression must be written based on these values. The correct calculation shows that the concentration of I2 is not 0.32 mol/L, and further analysis is needed to determine the accurate concentration. Understanding the equilibrium expression is crucial for solving this problem.

At 350degress celcius the equilibrium constant is 70. at equlilibrium the concentration if HI is 1.32 mol/L and that of H2 is 0.100 mol/L.
what is the concentration of I2?
would it be 0.32?

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...
