Model (b)has the largest rate constant Model (c) has the largest rate constant. ·D, The rate constant is equal intal and ? See Hint Part 2 (1point) Which model (al. (b), or ie) has the largest instantaneous rate of reaction? The reaction is not zero arder Choose one: . A Model (a) o B. Model b) o C. Model (c) D. The instantaneous rate is equal in models tal(b), and le. ° E Insufficient information is provided to predict the relationship. ? See Hint Part 3 (1 point) A plot of sdo of molecules is increased by a factor of 15 versus time is linear Using this information identify the factor by which the rate will increase in madel(cl ifthe number

Explanation / Answer

A plot of 1/NO2 versus time is linear . that represents the reaction is second - order .

Rate = k [NO2]^2

       = k [15 x NO2]^2

       = k x 225 [NO2]^2

rate = 225 k [NO2]^2

rate increases by 225 times
