Solution A Solution B Reaction Time 25s 50s 8) Based on the data table above, which of the following solutions has the highest molarity and why? A because it's faster. 9) Substance X reacts with the solutions. Which of the following would make the reaction happen the fastest, adding 10g of X as a pellet or 10g of X powdered, and why? 10g is has more power because it has more surface area so it gets hotter and faster. €
