Solution

## The gas compressibility factor (Z) tells us how much the real gas deviates from the ideal gas at a given pressure and temperature. Z=PVactualRT, For 1 mol of gas At point C, Z=1, but gas is not ideal in nature, force of attraction are equal to force of repulsion. As the pressure increases at a given temperature, initially attractive for increases between the molecules and hence the value of Z decreases but with further increase in pressure repulsive force dominates and Vactual increases gradually and corrspondingly value of Z also increases.
