In a reaction progress curve, which point on the curve corresponds to an intermediate of the reaction?

Answer : The valley between the two peaks is usually referred to intermediate formation of the reaction. The two mountain peaks when formed in a reaction the stable phase between them is exactly when an intermediate is formed and often observed on the curve.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
