NEET Chemistry (general) MCQ Question
Type: MCQ-fact-Medium-Class 12
In a reaction A(g) → B(g) + C(g), if the initial pressure of A is p_i atm and x atm is the decrease in pressure of A at time t, what is the expression for the partial pressure of A at time t?
A
p_i - x
B
p_i + x
C
2p_i - x
D
p_i + 2x
Correct Answer
Option A
Detailed Explanation
The decrease in pressure of A at time t is given as x atm, therefore the partial pressure of A at time t can be expressed as p_i - x. This follows from the relationship established in the equation for the reaction provided in the text.
