The equilibrium constant, keq, is 4.4 × 10-4 at 500 k. 2nocl (g) < --> 2no(g) + cl2 (g) determine the direction of reaction if 1.00 m nocl is combined with 0.500 m no and 0.500 m cl2 in a sealed flask. a.)no reaction occurs. b.)reaction proceeds to the right toward the products. c.)reaction proceeds to the left toward the reactants. d.)reaction proceeds to the left toward the products.

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
