To investigate the effect of changing various factors on the rate of a reaction, Kayla placed a conical flask onto a scale at room temperature and added 5.0g of Magnesium strip followed by excess hydrochloric acid. (a) Kayla repeated her experiment using 5.0g of Magnesium powder instead of the strip. What effect would you expect this to have on the rate of the reaction, (Increase or
decrease)? Explain your answer.

Effect:

Explanation:

(b) Kayla repeated her experiment again at 40°C, instead of room temperature. What effect would you expect this to have on the rate of the reaction. (Increase or decrease)? Explain your answer.

Effect:
