Two compounds, X X\,X and YYY, react in aqueous solution in the presence of a soluble catalyst, ZZZ, as shown in the equation:
2X+Y→W 2X + Y \rightarrow W 2X+Y→WWhen the concentration of X X\,X is doubled, and the concentrations of Y Y\,Y and Z Z\,Z are both tripled, the rate of reaction increases by a factor of 18.
Which is a possible rate equation for this reaction?
rate=k[X]2[Y]\text{rate} = k [X]^2 [Y]rate=k[X]2[Y]
rate=k[X][Z]\text{rate} = k [X] [Z]rate=k[X][Z]
rate=k[X][Y][Z]\text{rate} = k [X] [Y] [Z]rate=k[X][Y][Z]
rate=k[Y]2[Z]\text{rate} = k [Y]^2 [Z]rate=k[Y]2[Z]
