CHEM 113 1nd Edition Lecture 15 Outline of Last Lecture I. Solving Equilibrium ProblemsII. Practice ProblemOutline of Current Lecture II. Another solving equilibrium practice problemCurrent LectureSample Problem 17.8Problem- The first step to tackling this problem, is to balance the equation- Then we write out our equation for K concentration [H2]^3 [CO]o K= [CH4] [H2O]- Next we find the concentrations of H2, CO and CH4, so we can plug these values into theprevious equation.o We are given the amount of moles of each of these as well as a volume quantity of 0.32 L. Therefore we can find concentration.- We plug these values into our K equation to produce a [H2O] of 0.53 MThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- General concept for solving equilibrium problemso These types of problems will almost always require you to plug things into the K equation or Q equation (they are identical). The tricky part is just determining the values that go into them. Sometimes this requires you to think about the problem logically, other times may require you to use some of the techniques we used in classlike the “ICE
