Solution
The correct option is C zero
Its a zero order reaction
A→product
Ratelaw=k[A]0
A zero oredr reaction is the one which the rate is proportional to the zeroth power of the concentration.
The total pressure will not affect the pressure of the gas on the surface cannot change by increasing the pressure
