Butadiene, C4H6, dimerizes to C8H12 with a rate law rate = k[C4H6]2 where k = 0.84 L/(mol·min). What will be the concentration of C4H6 after 180 min if its initial concentration is 0.025 M?

Answer : The concentration of C₄H₆ after 180 min is, 0.0052 M

Explanation :

The integrated rate law equation for second order reaction follows:

where,

k = rate constant =

t = time taken  = 180 min

[A] = concentration of substance after time 't' = ?

= Initial concentration = 0.025 M

Now put all the given values in above equation, we get:

Hence, the concentration of C₄H₆ after 180 min is, 0.0052 M

it is a good conductor

explanation:

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.
