Question

The equation X + Y 2 Z has the rate law equation shown below. Which of the following statements best describes the relationship of X on the rate of the reaction?

rate = k[X]2[Y]

Answer 1

Changing X has no effect on the reaction rate.

Doubling X causes the reaction rate to quadruple.

Dividing X by two causes the reaction rate to be cut in half.

Multiplying X by three also increases the reaction rate by three times.

Answer 2

\[\text{rate} = k[X]^2[Y]\] ?

Answer 3

say \(X=2x\)

\[\text{rate}=k[2x]^2[Y]\]\[\qquad=k2^2[x]^2[Y]\]\[\qquad=4k[x]^2[Y]\]
