1. Below, consider the "molecular view as a function of time" of a container initially filled with
two gases, X2 and Y2, at room temperature. View A is the "molecular snapshot" of the reaction at
time = 2 seconds. In view B, 4 seconds have passed. In view C, 6 seconds have passed. In
view D, we are 8 seconds into the reaction. And in view E, we are 10 seconds into the reaction.
A
B
C
D
E
X is dark gray (purple) and Y is light gray (pink). X2(g) + Y2(g) <=> 2XY(g) Please see
Canvas for a color copy of this assignment if you have difficulty discerning the light gray and
dark gray.
a) Write the reaction quotient expression, Qc, for this reaction.
b) If each molecule represents 0.10 mol of molecules in 1.0 L, calculate Qe at each time point.
c) What is the value of K at this temperature?
