Phosphorous and chlorine gases combine to produce phosphorous trichloride: p2(g) + 3cl2(g) ⇌ 2pcl3(g)δg° at 298 k for this reaction is −642.9 kj. the value of δg at 298 k for a reaction mixture that consists of 1.500 atm p2, 1.600 atm cl2 and 0.650 atm pcl3 is

ΔG = -649,5 kJ

Explanation:

It is possible to answer this question using:

ΔG = ΔG° + RT lnQ

For the reaction:

P₂(g) + 3Cl₂(g) ⇌ 2PCl₃(g)

ΔG° = -642,9 kJ at 298K

R is gas constant (8,314x10⁻³ kJ/molK)

And Q is reaction quotient, for the present reaction

, where [P₂] = 1,500atm ;Cl₂ = 1,600atm; [PCl₃] = 0,650 atm

Replacing:

ΔG = -649,5 kJ

I hope it helps!

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.
