Whydoesthe reactionrateof areactionincrease onraisingthe temperature ? |

Answer» Solution :On increasing temperature heat is supplied to the reactant. This energy breaks more bonds and THUS speed up the chemical reaction. Foods kept at room temperature spoils faster than that kept in the refrigerator. (b) There are two major classes of double displacement reactions. They are, (i) Precipitation Reactions When aqueous solutions of two compounds are mixed, if they react to form an insoluble compound and a soluble compound, then it is CALLED precipitation reaction. `Pb(NO_(3))_(2(aq))+2KI_((aq))toPbI_(2(s))darr+2KNO_(3(aq))` (ii) Neutralisation Reactions Another type of displacement reaction in which the ACID reacts with the base to form a salt and WATER. It is called .neutralisation reaction. as both acid and base neutralize each other. `NaOH_((aq))+HCl_((aq))toNaCl_((aq))+H_(2)O_((1))` |
