Effect of Temperature on Rate of Reaction
 1) Rate of a reaction is given by Rate = Δconcentration/Δtime Rate = concentration/time Rate = time/concentration Rate = Δtime/Δconcentration

 2) A reaction 3X+6Y→Z, the rate of the reaction can be given by Rate=−Δ[X]/Δt=−Δ[Y]/Δt =Δ[Z]/Δt Rate=Δ[X]/3Δt=Δ[Y]/6Δt =Δ[Z]/Δt Rate=−Δ[X]/3Δt=−ΔY/6Δt =−Δ[Z]/Δt Rate=−Δ[X]/3Δt=−Δ[Y]/6Δt =Δ[Z]/Δt

 3) Factors which affect the rate of a reaction Nature of the reaction All of these Temperature Concentration

 4) Factors which do not affect the rate of a reaction Pressure All of these contribute to the rate of a reaction Catalyst Amount of the product formed

 5) Which gas is formed when Sodium thiosulphate react with hydrochloric acid O₂ N₂ SO₃ SO₂

 6) What is the formula of sodium thiosulphate Na₂S₂O₂ Na₃S₂O₂ Na₂S₂O₃ Na₃S₂O₃

 7) What type of solution of sulphur is obtained Precipitate solution Saturated solution Colloidal solution Salt solution

 8) The rate of a reaction increases with increase in temperature is due to Elastic collision Successful collision Increased energy and successful collision Increased energy

 9) Catalyst is a substance, which __________ chemical reaction. Alters the value of equilibrium constant in a reversible Increases the speed of a Decreases the speed of a Can either increase or decrease the speed of a

 10) According to Arrhenius equation , rate constant (k) is proportional to e^1/E e^E e^-E Activation energy E
