Problem

H2 and I2 are combined in a flask and allowed to react according to the following reaction: H2(g) + I2(g) ⇌ 2 HI(g)
Examine the figures (sequential in time) and answer the following questions.
The figure shows 6 sequential states of the reaction. There can be 3 kinds of molecules in the flask. The first consists of 2 purple balls connected together, the second consists of 2 white balls connected together, and the last is a purple and a white ball attached to each other. At picture 1, there are 10 purple and 10 white molecules in the flask. At picture 2, there are 7 purple, 7 white, and 6 purple-white molecules in the flask. At picture 3, there are 5 purple, 5 white, and 10 purple-white molecules in the flask. At picture 4, there are 4 purple, 4 white, and 12 purple-white molecules in the flask. At picture 5, there are 3 purple, 3 white, and 14 purple-white molecules in the flask. At picture 6, there are 3 purple, 3 white, and 14 purple-white molecules in the flask.
Which figure represents the point at which equilibrium is reached?
