1	For most of the chemical reaction the rate of reaction	Increases as the reaction proceeds Decreases as the reaction proceeds May increases or decreases during the reaction Remains constant as the reaction
2	The rate of a reaction can be increased in general by all the factors except by	Using a catalyst Increasing temperature Increasing the activation energy Increasing the conc. of reactants
3	The unit of rate constant for a zero order reaction is	Liter sec<sup>-1</sup> Liter <span style="font-size: 14.44444465637207px;">mol</span><sup>-1 </sup><span style="font-size: 14.44444465637207px;">sec</span><sup>-1</sup> Mol liter<sup>-1 </sup><span style="font-size: 14.44444465637207px;">sec</span><sup>-1</sup> Mol <span style="font-size: 14.44444465637207px;">sec</span><sup>-1</sup>
4	When KCIO₃ is heated it decomposes into KCI and O₂ if some MnO₂ is added the reaction goes much faster because	MnO<sub>2</sub> decomposes to give O<sub>2</sub> MnO<sub>2</sub> provides heat by reacting Better contact is provided by MnO<sub>2</sub> MnO<sub>2</sub> acts as a catalyst
5	The rate of reaction between A and B increases by a factor of 100 when the concentration with respect to A is increased 10 folds the order of reaction w.r.t A is	10 1 4 2
