Bromine gas is used in the insecticide industry. Suppose 0.680 M Br2 is heated to 1756 K, a temperature at which the halogen dissociates to form atoms as demonstrated by the reaction below. If Br2 is 13.3% dissociated at this temperature, calculate K.

Broomgas word in die insekdoder industrie gebruik. Veronderstel 0.680 M Br2 word verhit tot by 1756 K, 'n temperatuur waarby die halogeen dissosieer na atome soos gedemonstreer in die reaksie hieronder. Bereken K indien Br2 13.3% gedissosieer is by hierdie temperatuur.
