The increase in the rate of solvation with a rise in solvent temperature is mainly due to a(n): a. increase in the activaton energy
b. increase in the movement of molecules leading to more collisions,
c. None of the above

Sorry i think the answer is b

Convection is da answer my dood

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
