Correct answer: A-R,U, B-P,X, C-S,V, D-Q,W. (A) Zero order: [A] = a - kt. Plotting [A] vs t gives slope -k (R) and intercept a (U). (B) First order: log(a-x) = log(a) - kt/2.303. Slope -k/2.303 (P), intercept log a (X). (C) Second order: 1/(a-x) = 1/a + kt. Slope k (S), intercept 1/a (V). (D) Third order: 1/(a-x)^2 = 1/a^2 + 2kt. Slope 2k (Q), intercept 1/a^2 (W). Therefore, correct answer is A-R,U, B-P,X, C-S,V, D-Q,W.
