Which Way Will It Go?

The reaction quotient

An interactive lesson with 5 steps, about 5 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

• Q has K’s form with current concentrations.
• Q < K → forwards; Q > K → backwards; Q = K → equilibrium.

Steps

1. Q: the same fraction, any time
2. Already balanced
3. Predict the direction
4. Compute Q
5. Empty flask
