WebThe sign of Kp tells us the direction the PV moves relative to the CO change. The negative value found above means that as the CO goes up, the PV goes down. We see this “up-down” relationship in the plot. For a process where a CO increase causes the PV to move up, the Kp would be positive and this would be an “up-up” process.
