Consider this reaction What is the rate law for this reaction? NO 2 ( g ) + CO ( g ) → NO ( g ) + CO 2 ( g ) 1. rate = k [NO 2 ][CO] 2. rate = k [NO][CO 2 ] 3. rate = k [NO 2 ] 2 4. rate law cannot be determined from info. given Clicker Questions: [1.

For the reaction: 2A + B BA 2 Doubling [A] doubles the rate of the reaction. However, tripling [B] increases the rate 9 × . What is the correct rate law expression? 1. rate = k [A][B] 2. rate = k [A] 2 [B] 3. rate = k [A][B] 2 4. rate = k [A][B] 3

It is observed that the rate of the first order reaction, CH 3 NC( g ) CH 3 CN( g ) (rate law: rate = k[CH 3 NC] ), decreases as time increases. Why is this true? 1. The reaction is exothermic 2. [CH 3 NC] decreases with time 3. The activation energy, E a , increases with time 4. k decreases with time 5. All of the above effects cause the rate to decrease with time
