For the reaction 2NOCI 2NO + Cl, the rate constant k equals 0.020 L mol-1 s1 at a certain temperature. Determine how many minutes it would take for the NOCI concentration to drop from 0.024 M to 0.016 M. It would take minutes.

The reaction CH;Br(aq) + OH (aq) - CH3OH(aq) + Br (aq) is first order with respect to each reactant. At a certain temperature, when the concentration of CH3Br is 0.565 M and the

Calculate the reaction rate for each trial using an average of the time (in sec) for each trial

The rate for the reaction H2 (g) + Br2 (g) 2 HBr (g)is first order in both H2 and Br2 concentrations, and the rate constant k at 287 \deg C is 5.87\times 10-4 L mol-1 s-1. Suppose 1.00 L of H2 (g) at a concentration of 6.60\times 10-2 M is rapidly mixed with the same volume of Br2 (g) also at a concentration of 6.60\times 10-2 M. Calculate the time (in seconds) required for the H2 concentration to decrease to a value of 2.55\times 10-2 M. (Enter your answer to three significant figures.)
