y: CH 13 HW- Internet Explorer rin TER Part A For a certain reaction, Ke -467 and ke -961 10 M Calculate the value of the reverse rate constant, k, given that the reverse reaction is of the same molecularity as the forward reaction e Ho Express your answer with the appropriate units. Include explicit multiplication within u Express your answer with the appropriate units. Ineclude explicit mutiplication within units, for example to enter M.s include (multiplication dot) between each measurement. us View Available Hint(s) ic S Aree ent ettir k,= Value Units Submit

Explanation / Answer

Ans 1

Equilibrium concentration

Kc = forward rate constant Kf / reverse rate constant kt

Reverse rate constant kt = 9.61*10^-3 /4.67

= 0.002057 M-2 s-1

Ans 2

NO + Br = NoBr

Kc = [NoBr] / [No] [Br]

= 0.25/(0.400*0.265)

= 2.358
