Based on these data, the rate constant for the reaction is ?

Question

The decomposition of nitrosyl bromide at 10 °C

NOBrNO + ½ Br₂

is second order in NOBr.

In one experiment, when the initial concentration of NOBr was 0.347 M, the concentration of NOBr dropped to 5.48×10^-2 M after 13.8 seconds had passed.

Based on these data, the rate constant for the reaction is _____ M^-1 s^-1.

Answer 1

Answer is: k= 1.114 M^-1s^-1
