Answer to Question #169439 in Chemistry for Phyroe

Question

Calculate K for the reaction 2A + B⇌C + D

if at equilibrium A = 0.4 formula weights/liter, B = 0.5 formula weights/liter , C = 0.3 formula weights/liter, and D = 0.8 formula weights/liter.

Answer 1

Solution:

For the reaction,

2A + B ⇌ C + D

the equilibrium constant (K) is defined by the following expression:

Hence,

K = 3

[Units of K] = ([fw/liter] × [fw/liter]) / ([fw/liter]² × [fw/liter]) = liter/fw = liter/formula weights

Answer: K = 3 liter/formula weights.
