Question

this image shows two setups for a reaction between magnesium and an acid. which setup will likely have the faster reaction rate? low surface area setup! high surface area setup! need temperature data to determine same reaction rate

Explanation:

The rate of a chemical reaction is affected by surface - area. A higher surface - area allows more reactant particles to be exposed and interact, increasing the reaction rate. In the case of the reaction between magnesium and an acid, the high surface - area setup provides more contact between magnesium atoms and acid particles.

Answer:

B. High Surface Area setup!
