Apply ideal gas and real gas reasoning

Paper 1, Paper 2 5 marks Difficulty 5

Real gas deviation from ideal behaviour

In a school extension lab, an ideal gas model predicts compressibility factor \(1\), but the real gas value is \(0.92\). Calculate the deviation from ideal. Enter the answer and choose the interpretation that matches the chemistry.

Worked practice: chemistry evidence and answer

Use the chemical evidence first, then enter the result and interpretation that match it.
