Methyl iodide reacts irreversibly with azide ion with rate = k[CH31][N3-]. CH31(aq) + N3(aq) → CH3N3(aq) + I-(aq) The reaction is carried out with an initial concentration of CH I of 0.01 M. Which statement about the reaction is correct? (A) The time it takes for [CH3I] to decrease to 0.005 M is independent of [N3-], as long as [N3] >> [CH3I].
(B) If the initial concentrations of azide and CH3I are equal, then it takes half as long for [CH3I] to decrease to 0.005 M as it does for it to decrease from 0.005 M to 0.0025 M.
(C) The reaction rate is significantly smaller if excess I- is added to the solution.
(D) The reaction cannot take place in a single elementary step.

Achemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2 no(g) + cl2(g) < => 2 nocl(g) kp = 2 x 10^(-6)he fills a reaction vessel at this temperature with 13. atm of nitrogen monoxide gas and 12. atm of chlorine gas. use this data to answer the questions: a. can you predict the equilibrium pressure of noci, using only the tools available to you within aleks? y/nb. if you said yes, then enter the equilibrium pressure of nocl at right. round your answer to 1 significant digit.
