In the gas phase at 400 ∘C, isopropyl alcohol (rubbing alcohol) decomposes to acetone, an important industrial solvent: (CH3)2CHOH(g)⇌ (CH3)2CO(g)+H2(g) ΔH∘ = +57.3kJ Isopropyl alcohol Acetone Does the amount of acetone increase, decrease, or remain the same when an equilibrium mixture of reactants and products is subjected to the following changes?
Multiple choice
Part A
The temperature is increased.
a) The amount of acetone will increase.
b) The amount of acetone will decrease.
c) The amount of acetone will remain the same. The volume is increased.
Part B
The volume is increased.
a) The amount of acetone will increase.
b) The amount of acetone will decrease.
c) The amount of acetone will remain the same.
Part C
Argon is added.
a) The amount of acetone will increase.
b) The amount of acetone will decrease.
c) The amount of acetone will remain the same.
Part D
H2 is added. is added.
a) The amount of acetone will increase.
b) The amount of acetone will decrease.
c) The amount of acetone will remain the same.
Part E
A catalyst is added.
a) The amount of acetone will increase.
b) The amount of acetone will decrease.
c) The amount of acetone will remain the same.
(CH3)2CHOH(g)? (CH3)2CO(g)+H2(g) ?H? = +57.3kJ
?H? is positive that means reaction is endo thermic reaction
Part A
Acetone will increase
because for endo thermic reaction if you increase the temperature reaction will favoured to wards right side
Part B
The amount of acetone will decrease.
if you increase the volume reaction is backward means no of moles will decrease
PartC
The amount of acetone will remain the same.
Argon is a nuetral gas it doesnt affect the equilibrium
PartD
The amount of acetone will decrease
if you add the right side component extra reaction shift backward
Part D
c) The amount of acetone will remain the same.
catalyst will only increase the speed of the reaction it doesnt effect the equilibrium
