The dissociation of 
takes place as per the equation 
(s) 
(s) 
(g); 
. If the reaction is carried out in a closed vessel, the pressure of 
increases and reaches a constant value when
A
Temperature is increased
B
Temperature is decreased
C
Volume of vessel is increased
D
Amount of 
is decreased
is decreased
Text Solution
Verified by ExpertsThe correct answer is:
A
Decomposition of 
is endothermic reaction. The forward reaction is favored by increasing temperature. Thus, when the temperature is increased, more carbon dioxide is formed which increases the pressure of carbon dioxide until it reaches a constant value.
