Question
For a third order reactions : 3X → Y + Z the initial rate is 5 × 10-2 mol L-1S-1 when the conc. of X is 0.1 mol L-1. The value of rate constant for the reaction is :-
Options
A.5 × 10-2 L2 mol-2 S-1
B.5 × 10-3 L2 S-1
C.5 × 10-4 L2 mol-2 S-1
D.50 L2 mol-2 S-1
Solution
∵ r = K [X]3 ⇒ 5 × 10-2 = K (0.1)3
⇒ K = 50 L2 mol-2 s-1
⇒ K = 50 L2 mol-2 s-1
