Question

For the chemical reaction $x⟶y$, it is found that the rate of reaction increases $2.25$ times when the concentration of $x$ is increased $1.5$ times. What is the order of reaction?

• A. One
• B. Two
• C. Three
• D. Zero

Answer 1

Answer: (B)

Two

$r=k{\left[x\right]}^a$ and $2.25r=k{\left[1.5x\right]}^a$
So, $2.25={\left(1.5\right)}^a$ or $a=2$
