Re: Chemical Kinetics EAMCET
Here I am providing list of few Chemical Kinetics questions of Engineering, Agriculture and Medical Common Entrance Test (EAMCET) which you are looking for . The rate constant of a first order reaction is 0.0693min-1. What is the time required (in minutes) for reducing an initial concentration of 20mol lit-1 to 2.5 mole lit-1 (2009 M) 1) 40 2) 30 3) 20 4) 10 Ans : 2 For a first order reaction at 270C the ratio of time required for 75% completion to 25% completion of reaction is (2009 E) 1)3.0 2) 2.303 3)4.8 4) 0.477 Assertion(A): A catalyst increases the rate of a reaction. Reason (R): In presence of a catalyst, the activation energy of the reaction increases. The correct answer is: 1. Both A and R are true and R is the correct explanation of A 2. Both A and R are true and R is not the correct explanation of A Chemical Kinetics 3. A is true but R is not true 4. A is not true but R is true Ans : 3 EAMCET Chemical Kinetics questions |
