A given chemical reaction system is defined by a balanced net chemical equation which is conventionally written as. reactants→ products (11.1.1) (11.1.1) reactants → products. the first thing we need to know about a chemical reaction represented by a balanced equation is whether it can actually take place. ️free notes: bit.ly class11chemistryequilibriumnotes ️free ncert solutions: bit.ly class11chemistryequilibrium ️complete playlist :. Figure 13.2.1 13.2. 1: a mixture of no2 no 2 and n2o4 n 2 o 4 moves toward equilibrium. colorless n2o4 n 2 o 4 reacts to form brown no2 no 2. as the reaction proceeds toward equilibrium, the color of the mixture darkens due to the increasing concentration of no2 no 2. a three part diagram is shown. Chemical equilibrium is the condition of a system where the concentrations of the reactants and products do not change with time. also, the system does not show any change in its properties. during a reversible reaction, when the forward and reverse reaction rates become equal, the system achieves the state of chemical equilibrium.
