<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
A catalyst is defined as the substance which increases the rate of the reaction without actually participating in the reaction.
This substance decreases the activation energy of the reactants, so as to proceed the reaction at a faster rate by increasing their effective collisions.
It does not affect the concentration of the reactants.
For the given reaction:
If we add NO, which is acting as a catalyst will increase the rate of the reaction to produce the products which is
Hence, the correct answer is Option A.
The equilibrium pressure of is 288 torr. and
for this reaction is 0.786 atm.
from the reaction:- ⇄
initial concentration 392 torr. 0
at equilibrium. 392 - .
and the final pressure in the flask = 488 torr.
Hence,
The partial pressure of is 3 × 96 = 288 torr.
and is 392 - ( 2 × 96 ) = 392 - 192 = 200 torr.
Now, to find for this reaction, we will use
putting all the values, we get,
= 597.1968 torr.
= 0.786 atm. ( 1 atm = 760 torr. )
what do you mean by equilibrium?
Equilibrium in chemistry is the phase that exists when a chemical reaction and its opposite reaction happen at the same rates. This word's Latin origin dates back to the prefix aequi-, which means equal, and lbra, that indicates scale or balance.
