The compressibility factor of a real gas is given by . At temperatures significantly above the Boyle — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Above the Boyle temperature, thermal energy dominates over attractive forces. Consequently, the effect of molecular size (repulsion) is the only significant deviation, causing $Z$ to be strictly greater than $1$ and increase steadily with pressure ($Z = 1 + Pb/RT$).
