Q: According to Graham's law of effusion, the rate of effusion of a gas is inversely proportional to what?

Solution: Graham's law states that the rate of effusion is inversely proportional to the square root of the molar mass of the gas.

Steps: 6

Step 1: Understand what effusion means. Effusion is the process of gas escaping through a tiny hole into a vacuum.
Step 2: Learn about Graham's law. It describes how different gases effuse at different rates.
Step 3: Know that the rate of effusion refers to how quickly a gas escapes.
Step 4: Identify the key relationship in Graham's law: the rate of effusion is related to the molar mass of the gas.
Step 5: Remember that 'inversely proportional' means that as one value increases, the other value decreases.
Step 6: Conclude that according to Graham's law, the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
