By what factor does the rate change in each of the following cases (assuming constant temperature)?
Factor (enter as decimal if <1)
(a) A reaction is first order in reactant A, and [A] is doubled.
(b) A reaction is second order in reactant B, and [B] is halved.
(c) A reaction is second order in reactant C, and [C] is tripled.

a) The rate of reaction increases by factor of 2.

b) The rate of reaction increases by factor of 0.25.

c) The rate of reaction increases by factor of 9.

Explanation:

a)

Rate of the reaction ;

if [A] is doubled, then rate of the reaction = R'

The rate of reaction increases by factor of 2.

b)

Rate of the reaction ;

if [B] is halved, then rate of the reaction = R'

The rate of reaction increases by factor of 0.25.

c)

Rate of the reaction ;

if [C] is tripled, then rate of the reaction = R'

The rate of reaction increases by factor of 9.

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.

hope this .

i think its 5049.

i hope this !
