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.

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

1. they vary with a higher number because boiling is way hotter than melting
