Question 11 Tries remaining: 1 Points out of 1.00 P Flag question What will happen if NH3CH3Br is added to the equilibrium reaction below? NH.CH(aq) + H200 NHCH(ag) + OH-(0) Multiple tries are permitted; however, 25% (1/4) point will be deducted for each incorrect response. Select one The concentration of products will decrease and the concentration of reactants will increase Both the concentration of products and reactants will increase The concentration of reactants will decrease and the concentration of products will increase. The equilibrium reaction will not be affected. Both the concentration of products and reactants will decrease. Check

Answer 1

Option C. The concentration of reactants will decrease and the concentration of products will increase.

$NH_{3}CH_{3}Br$, when added to the reaction mixture, dissociates into,

$NH_{3}CH_{3}Br\rightleftharpoons NH_{3}CH_{3}^{+}+Br^{-}$

Now, in the provided equilibria, the species, $NH_{3}CH_{3}^{+}$ is on the product side, so if we add this species in the equilibrium mixture, we are actually increasing the concentration of the products and this will lead the backward reaction to intensify in rate so that the equilibrium could be reestablished.
