What is Rate of Reaction
How fast or slow a reaction is.
Magnesium Block has a ________ surface area compared to Magnesium Powder ( If both have the same mass ) .
Lesser / Lower Surface Area
How can decrease in temperature affect the rate of reaction?
The rate of reaction will become slow.
Does a concentrated acid react faster than aur slower than a dilute acid
What does the slope forgredient tell you about the graph .
How quickly the reaction is taking place.
What product is formed when you burn magnesium ribbon with bunsen burner .
Magnesium Oxide
How do you come to know that reaction is stopped
The bubbling has stopped or the graph shows of horizontal line
What do you mean by concentration ?
A measure of how many particles of a substance are in a fixed volume of a solution
What do you use to collect gas
Syringe
What does surface area mean?
Surface area is the total area of a solid reactant exposed to other substances
What does sleeper slope represent
Faster Reaction
What does an anomalous result mean?
A piece of data that does not fit the pattern of the other results in an experiment.
What is the formula to calculate Rate of Reaction
Amount of Gas produced / Time Taken
Each time you cut solid into smaller pieces what happens to the surface area ?
The surface area increases.
How does temperature affect particle speed
If the temperature increases the particles speed also increases
Is the temperature decreases the particle speed also decreases
If you increase the concentration of hydrochloric acid reacting with magnesium ribbon, what happens to the rate of reaction, and why?
The rate of reaction increases. This is because there are more particles leading to more frequent collisions between the reactant particles.
What is the chemical symbol and salt endings for
Nitric Acid
Sulfuric Acid
Nitric Acid - HNO3 , Salts end with Nitrate
Sulfuric Acid - H2S04 , Salts end with sulfate
Why does larger surface area has faster Rate of Reaction
The larger the surface area, More particles are exposed to other substances creating more vigorous and frequent collisions.
Why does increasing temperature fasters the rate of Reaction
As temperature increases , Particles gain more kinetic energy , collide much stronger and frequently leading to more collisions that eventually fasters the rate of Reaction
Explain the effect of concentration using particle theory.
The higher the concentration of acid the more the acid particles are there in a given amount of space this means that there will be more frequent collisions between acid particles and the other substance particles
