Step-by-step solution
The slope of a linear plot is determined by comparing its equation to the straight-line equation y = mx + c , where m is the slope. A. For a zero-order reaction, the integrated rate equation is [R] = -kt + [R]₀ . A plot of [R] versus t gives a straight line with a slope of -k . (A matches IV) B. For a first-order reaction, the differential rate law is Rate = k[R] . A plot of Rate versus [R] gives a straight line passing through the origin with a slope of k . (B matches I) C. For a first-order reaction, the integrat
