NEET Chemistry (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram representing the change in partial pressures during the reaction A(g) → B(g) + C(g) over time. If the initial pressure of A is p_i atm, what is the expression for the partial pressure of A at time t?
A
2p_i - p_t
B
p_i + x
C
p_i - x
D
p_t - p_i
Correct Answer
Option A
Detailed Explanation
The partial pressure of A at time t is given by p_A = 2p_i - p_t, derived from the relation p_A = p_i - x where x = p_t - p_i.
