Nitrosyl chloride, NOCl, dissociates on heating as shown below. When a 1.50-gram sample of pure NOCl is heated at 350°C in a volume of 1.00 liter, the percent dissociation is found to be 57.2%. Calculate the equilibrium concentration of NOCl.
NOCl(g) NO(g) + Cl2(g)
a. 8.76 × 10^−1 M
b. 9.26 M
c. 9.80 × 10^−3 M
d. 1.31 × 10^−2 M
e. 1.75 × 10^−4 M
Answer: c. 9.80 × 10−3 M
