How Do You Measure The Rate Of A Reaction?
Answer: By Measuring The Quantity Of A Reactant Used Or The Quantity Of Product Formed
Over Time
What Is The Equation For Calculating The Mean Rate Of A Reaction By Measuring The Amount
Of Reactant Used?
Answer: Mean Rate Of Reaction = Quantity Of Reactant Used/Time Taken
What Is The Equation For Calculating The Mean Rate Of A Reaction By Measuring The Amount
Of Product Formed?
Answer: Mean Rate Of Reaction = Quantity Of Product Formed/Time Taken
What Units Can You Measure The Rate Of A Reaction In?
Answer: G/S Or Cm3/S Or Mol/S
How Do You Calculate The Rate Of A Reaction At A Specific Time From Graph Of The Quantity Of
Reactant Used Or The Quantity Of Product Formed?
Answer: By Measuring The Gradient Of A Tangent Drawn At That Specific Time On The Graph
, What Are The Five Factors That Can Affect The Rate Of A Reaction?
Answer: Concentration Of Reactants In Solution, Pressure Of Reacting Gases, Surface Area Of
Solid Reactants, Temperature And The Presence Of A Catalyst
What Theory Can We Use To Explain How Various Factors Affect The Rate Of A Reaction?
Answer: Collision Theory
What Is Collision Theory?
Answer: Chemical Reactions Can Occur Only When Reacting Particles Collide With Each Other
And With Sufficient Energy
What Is The Activation Energy Of A Reaction?
Answer: The Minimum Amount Of Energy That Particles Must Have To React
According To Collision Theory Why Does Increasing Concentration Of Reactant In Solution
Increase The Rate Of The Reaction?
Answer: It Increases The Frequency Of Collisions And So Increases The Rate Of Reaction
According To Collision Theory Why Does Increasing The Pressure Of Reacting Gases Increase The
Rate Of The Reaction?
Answer: It Increases The Frequency Of Collisions And So Increases The Rate Of Reaction
