Question

For a second order reaction rate at a particular time is $x$. Ifthe initial concentration is trapled, the rate will becomes?

• A. $3x$
• B. $9x^2$
• C. $9x$
• D. $27x$

Answer 1

The correct option is C $9x$

Its a second Order reaction.

The rate at a particular time is x.

$x=k{\left[A\right]}^2$

If the initial concentration is tripled, the rate becomes

$rate=k\left[{3\left[A\right]}^2\right]$ = $9x$
