What is the correct interpretation?

At higher temperature, less gas is produced At higher temperature, rate of reaction is slower Gas solubility increases at higher temperature Higher temperature increases reaction rate

What does this graph show about catalyst?

Catalysts increase activation energy Catalysts make reactions slower Catalysts provides a more efficient reaction pathway Catalysts reduce activation energy needed

What conclusion can be made?

Higher temperature increases reaction rate Rate decreases with temperature Reaction becomes reversible at 50°C Temperature has no effect

What does this bar graph of volume of gas produced against concentration demonstrate?

Higher concentration increases rate of reaction Lower concentration gives more gas Rate increases with decreasing concentration Reaction yield increases with concentration

What is the relationship?

Particle size has no effect Powdered CaCO₃ reacts slower Rate increases as surface area increases Surface area decreases rate
