If the reaction below is initially at equilibrium, and then each of the following changes are made, predict which direction the reaction rate will be fastest until equilibrium is once again established: forward, reverse, or no change. H2(g) + Cl2(g) + 2 HCl(g) a. the concentration of H₂ is increased forward b. the concentration of HCl is decreased forward c. the concentration of Cl₂ is decreased versc 2. If the reaction below is initially at equilibrium, and then more NH4+ is added, predict which direction the reaction rate will be fastest until equilibrium is once again established: forward, reverse, or no change. Forward If more Hu is added Hut reactant If more wHyt added, forward NH4+ (aq) + H₂O (1) reaction fast until equilibrium reestablished NH3 (aq) + [30+ (aq) 3. Define (a) reversible reaction and (b) equilibrium. A.) Reversible reaction is produce original reactant, one where the products of the reaction can themselves react to B.)

Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
