Question

For a reaction $A+B\to$ Products, the rate of the reaction was doubled when the concentration of $A$ was doubled the rate was again doubled when the conc. of $A$ & $B$ were doubled. The order of reaction with respect to $A$ & $B$ is:

• A. $1,1$
• B. $2,0$
• C. $1,0$
• D. $0,1$

Answer 1

Answer: (C)

$1,0$

Let the rate of reaction can be given as:

$rate=k\left[A\right]\left[B\right]$

When the Concentration of A was doubled, the rate was doubled

Which Implies Order of Reaction wrt A is 1.

When Concentration of A and B was doubled, the rate was doubled

Which Implies Order of Reaction wrt B must be 0.

So Option C is correct
