MDCAT Chemistry Chapter 7 Reaction Kinetics Online Test

Sr. # Questions Answers Choice
1 The enthalpy of formation of a compound is Positive Either positive or negative Negative None
2 The values of ∆H for the process l(g)+e-1--------->
I-1(g) is:
>0 <0 0 None
3 Calorie is equivalent to 0.4184J 4.184J 418.4J 40.18J
4 If a reaction involves only solids and liquids, which of the following is true? ΔH = ΔE ΔΗ =ΔΕ ΔH>ΔΕ AH =AE +nRT
5 NaOH+HCI- NaCI+ H2O. Enthalpy change in the above reaction is called Enthalpy of reaction Enthalpy of Neutralisation Enthalpy of formation Enthalpy of combustion
6 Hess's law is analogous to Law of heat summation law of increasing entropy Law of heat exchange Ist law of thermodynamics
7 The net heat change in a chemical reaction is the same whether it is brought about in two or more different ways in one or several steps.it is known as Henry's law Hess's law joule's law Law of conservation of energy
8 Which of the following has positive value of enthalpy Neutralisation Atomization combustion All of the above
9 For an endothermic reaction, enthalpy of reactants Is smaller than that of the products Is greater than that of the products Must be greater or smaller than that of the products Is equal to that of the products
10 Enthalpy of neutralization of strong acids and strong bases have same values because Neutralization leads to the formation of salt and water Acids always give rise to H+ and bases always furnish OH- Strong acids and bases are ionic substances The net change involves the combination of H and OH ions to form water
