For the gaseous reaction 2A + B ⟶ C + D, the rate is given by k [A] [B]. The volume of the container containing the reaction mixture is suddenly reduced to one fourth of its original volume. with respect to the original rate, now the rate would be
A.1
B.1
C.16 times✓ Correct
D.8 times
Explanation
Original Rate; 1 R k A B As 1 C V , Now, volume is reduced to one-fourth of its original volume. so concentration is increased four times. So, new concentration, 4 4 A A B B Thus, new rate; 4 4 x x R k A B 1 16 16 x k A B R
