Textbook Problem 11.47

Postby Abby Ellstrom 1I » Fri Nov 24, 2017 2:23 pm

I am very confused as how to find the percent decomposed of a reactant. When using the ICE table for this problem, I keep getting that PCL3 is 73% decomposed.

For part a for 11.47 I got x=.01 mol per Liter.

For part b, the question is asking what percentage of the PCL5 has decomposed at equilibrium. Since x=.01 mol per Liter, we know that at equilibrium the concentration of PCl5 is .009 mol per Liter. That means .01 M of PCl5 has decomposed.

.01 M divided by .019 M (initial concentration)= 53%.
