Question:

Suppose you start with a mixture of 1.00 mol CO and 4.00 mol H2 in a 10.00-L vessel. Find the moles of substances present at equilibrium at 1200 K for the reaction

You will get an equation of the form
f (x) = 3.92
where f(x) is an expression in the unknown x (the amount of CH4). Solve this equation by guessing values of x, then computing values of f(x). Find values of x such that the values of f(x) bracket 3.92. Then choose values of x to get a smaller bracket around 3.92. Obtain x to two significant figures.
