1.	How does the rate of a reaction depend upon the temperature of reactants ? Give a suitable example ?
Answer» Solution :(1) When the temperature of the reactants is increased, the reactant molecules start moving with more velocity and their kinetic energy increases. As a result, the number COLLISIONS increases. Hence the rate of chemical reaction inreases. (20 Lime stone on heating decomposes to give ` CO_(2)` , which turns lime water milky. on the other hand, the lime water does not turn milky before heating the lime stone : because of the zerorate of reaction . The above observation indicates that the rate of a reaction inreases. on increasing the temperature. (ii) Solid ` CaCO_(3)` does not decompose at room temperature when HEATED, it decomposes to give CaO and ` CO_(2)`that means the rise in temperature increases the rate of reactions. ` CaCO_(3) OVERSET(" Room temperature ")to ` No Chemical reaction. ` CaCO_(3)overset(Delta)to CaO + CO_(2) uarr`
