Sr. # Questions Answers Choice
1 The rate determinig step in a multistep reaction is The slowest step Always the first step Always the last step The fastest step
2 If we double the conentration of a reactant, the rate increases by four times, the reactionis. First Order Second Order Third Order Zero order
3 On a Boltzmann distribution curve, the activation energy is represented by The height of the peak The area under the entire curve A vertical line drawn at a specific kinetic energy value The difference between the peak and the X axis
4 On Boltzmann distribution curve, the area under the curve represents. Activation energy of the rreaction Total numebr f moleclues in the sample Average kinetic energy of the molecules Rate constant of the reaction
5 The order of a chemicla reaction, that is dependent of concentration is. Second order reaction First order reaction Zeroorder reaction Pseudo first order reaction
6 Considr two reactions with different activation energies at the same temperature, The reaction with the lower activation energy will have A smaller rate constatn A larger rate constant The same rate constant A rate constant that depends on the enthalpy change
7 Increasing the temperature of a chemical reaction increases the rate of a reaction because. Both the collision frequency and collision energies of reactant molecules increase Collision frequency of reactatn molecule increases Activation energy increase Activiation energy decrease
8 The rate of reaction . Increase as the reaction proceeds Decreases as the reaction proceeds Remains the same as the reaction proceeds May decrease or increse as the reaction proceeds
9 AG = 0 indicates Equilibrium Spontaneity Non Spontaneity Irreversibility
10 Which is not a path function Work Heat Entropy Temperature
11 An increase in entropy favors  Non spontaneity Disorder Order Equilibrium
12 A process with increase in entropy and enthalpy is spontaneous at. High temperature Low temperature All temperature never spontaneous
