Calculate K c for the reaction 2HI(g) H 2(g) + I 2(g) given that the concentrations of each species at equilibrium are as follows: [HI] = 0.85 mol/L, [I 2] = 0.60 mol/L, [H 2] = 0.27 mol/L.

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.
