For a linear equation, y=mx, to determine the order of a schematic reaction: a→b using integrated rate laws, which variables must be applied to x, y, and m?
1) x: time, y: concentration of a, m: rate constant
2) x: concentration of a, y: time, m: rate constant
3) x: rate constant, y: time, m: concentration of a
4) x: rate constant, y: concentration of a, m: time
