## Ashja Group Title 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] one year ago one year ago

1. Ashja Group Title

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.

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

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