Ans:- (i) Gluconic acid - Kendriya Vidyalaya No.2, Kribhco, Surat
... Ans: Negative type of deviation is present. In the negative deviation the solute-solution (A-A) interaction and solvent-solvent (B-B) interaction will be weaker than solute-solvent(A-B ) interaction. Since the new forces are stronger therefore heat is evolved and solution becomes warm. Q13. Which ty ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
