The question seems to be incomplete and vague. So, I am giving an assumed answer.
In the air-standard Otto cycle, P₂, P₃, and P₄ are designated for the terminal pressure usually at the end of the compression, the heat release, and the expansion.
If the variable-specific heat and the dissociation of the working fluid are taken into account, and the corresponding values are considered to be P₂' P₃', and P₄', then the - P₂ > P₂' and the P₃ > P₃'.
The Otto cycle with the constant specific heat is represented by solid lines and the dotted lines represent the Otto cycle with the variable specific heats. So, at the end of the compression, P₂ will be greater than P₂' (P₂ > P₂') and at the end of the heat addition, P₃ will be greater than P₃' (P₃ > P₃').
