Question

What is the equilibrium concentration of ibr?

Answer 1

IBR is the thermal decomposition of iodine(I) bromide to produce iodine and bromine. This reaction takes place at a temperature of over 40,5°C and is written as: 

 2IBr ⇄ I2 + Br2

Equilibrium is a state of dynamic balance where the ratio of the product and reactant concentrations is constant. You can calculate the equilibrium concentration if you know the equilibrium constant Kc (Kc=I^2*Br^2/IBR^2) and the initial concentration for the reaction. The initial concentration is obtained from ICE Table.
