The activation energy for a reaction can be None of these Increased by decreasing temperature Increased by increasing temperature Decreased by increasing concentration of reactants Question 1 of 10Question 2 of 10 2. If a reaction proceeds in such a way that order of reaction is independent of the reactants concentration, the overall order of reaction would be Zero Second Third First Question 2 of 10Question 3 of 10 3. The rate of a reaction _________ as the reaction proceeds. Increases Decreases Remains the same May increase or decrease Question 3 of 10Question 4 of 10 4. The unit of the rate constant in the same as that of the rate of reaction in ________ order reaction. Third Zero Second First Question 4 of 10Question 5 of 10 5. Rate law for the reaction R-X + H₂O → R-OH + HX is, rate = k[R-X]. The rate of reaction will be doubled when None of these Concentration of H₂O is doubled Concentration of R-X is reduced to half Concentration of both R-X and H₂O is doubled Question 5 of 10Question 6 of 10 6. Reactions with high activation energy are usually Exothermic Slow Fast Reversible Question 6 of 10Question 7 of 10 7. For the reaction 2A + B → C, the rate law for the reaction is Rate = k[A][B] Rate = k[C] Rate = k[A]²[B] None of these Question 7 of 10Question 8 of 10 8. For the reaction 2A + B → C + D The expression for the rate law is, rate = k[A]², the order of reaction in B is: Second First None of these Third Question 8 of 10Question 9 of 10 9. In a reversible reaction catalyst lowers the activation energy of the Forward reaction Reverse reaction Forward reaction but increases for the reverse reactionForward as well as reverse reaction Question 9 of 10Question 10 of 10 10.
