Question

For cases where [A] exactly doubles: • if the rate does not change, the order for A is 0. • if the rate doubles, then the order for A is 1. • if the rate quadruples, the order for A is 2. For more complex cases, use the general equation: ratei [reactant), order rate '[reactant]2 What is the reaction order with respect to A? [A], mol/L [B], mol/L Trial 1 0.694 0.432 rate, mol/(L-min) 0.0752 Trial 2 1.39 0.432 0.0752 Trial 3 0.694 0.864 0.150 Trial 4 0.993 0.913 0.159 Rate = k[A]orderApBjorderB

Answer 1

. As it is given that Reten Rate, order . Reactent Perekent, order Reactent, Ratez [B] M/L 2999999999999 Trial ! Trial 2 [A] mol/L 0.694 1.89 0.432 rate, mol/(L-min) 0.0752 0.6752 0.432 So with respect to T 0.0 752 (1.30, order 0.0752 0.694 ) so Order With Respect to A is Zero. [A] Holle [5] Moth rate mol/L-min 0.432 0.0752 2 Trial L 0694 Trial 0.694 So with respect to B 0.864 0 /50 0.8141 order 0.150 0.0752 0. 880 .150 = (0432) So Order with respect w to B is 1. 2 - (2) f Rake = K[A]ª[B]
