Given the following rate law, how does the rate of reaction change if the concentration of Y is quadrupled?

Rate = k[X][Y]0.5

the rate of reaction increases by a factor of 4

the rate of the reaction decreases by a factor of 4

that rate of reaction is constant

the rate of reaction decreases by a factor of 2

the rate of reaction increases by a factor of 2

The rate of reaction increases by a factor of 2.
