$A + 2 B \to C$ , the rate equation for the reaction is given as

Rate $=k [A] [B]$

If the concentration of A is kept the same but that of B is doubled what will happen to the rate itself?

Correct answer
A
Doubled
B
Halved
C
The same
D
Quadrupled

Solution

R_{1} = k [A] [B]

R_{2} = k [A] [2 B]

∴ \frac{R_{2}}{R_{1}} = 2

Hence, the correct answer is option: 'A'.
