[6] A plot of 1/[BrO-] vs time is linear for the reaction:   3 BrO- (aq)  →  BrO3- (aq)  +  2 Br- (aq) What is the order of the reaction with respect to the hypobromite ion?

[20 Which of these neutralization reactions has a pH < 7 when equal molar amounts of acid and base are mixed?

[31] What is the shorthand notation that represents the following galvanic cell reaction? MnO4- (aq) + 16 H+ (aq) + 10 I- (aq)  →  5 I2 (s) + 2 Mn2+ (aq) + 8 H2O (l)

[30] At normal atmospheric pressure, the partial pressures of the reaction mixture are: 2 CO (g)  +  2 NO (g)  ↔  2 CO2 (g)  +  N2 (g) Which direction will the reaction shift?       CO NO CO2 N2   P (atm) 5.0 × 10-5 5.0 × 10-7 3.0 × 10-4 0.80

[3] The gas-phase reaction of A and BC, is second order in A and first order in BC. What is the rate law, and what are the units of the rate constant? A2 (g)  +  2 BC (g)  →  2 AB (g)  +  C2 (g)

[8] The equilibrium constant (KP) for the formation of nitric oxide at 530 °C is 2.9 × 10-11. Calculate what the partial pressure of NO when the partial pressures of nitrogen and oxygen are 3.0 and 0.12 atm, respectively. N2 (g)  +  O2 (g)  ↔  2 NO (g)

[5] The following mechanism has been proposed for the reaction of nitric oxide and chlorine: NO (g)  +  Cl2 (g)  →  NOCl2 (g)          Step 1 NOCl2 (g)  +  NO (g)  →  2 NOCl (g) Step 2 What is the overall reaction?

A chemical producer’s marginal social cost (MSC) lies above marginal private cost (MPC). The market outcome results in:

A local government funds mosquito control because the benefits extend across entire neighborhoods. It would be difficult to exclude individual households from reduced mosquito exposure once spraying occurs. The strongest reason private markets may underprovide mosquito control is:

Under a cap-and-trade system, firms with low pollution-control costs often sell unused permits to firms with higher cleanup costs. The main economic advantage of this system is that it:
