Here are the results of the 3 trials of dissolving equal masses of marble in hydrochloric acid listed from fastest to the slowest.

Question

List concentration, surface area, and temperature in decreasing order of their important in increasing the rate of this reaction.

Trial 1 = Dilute = Marble is finely ground = 20 degrees C
Trial 2 = Dilute = Marble is Lump = 40 degrees C
Trial 3 = Concentrated = Marble is lump = 40 degrees C

Answer 1

I see the trials but no results. Look at your results and arrange them in the order requested. Or are you doing a dry lab of the experiment.

Answer 2

The results are there for each trial
Trial 1 = Hydrochloric Acid is dilute. Marble is finely ground and the temperature is 20 degrees Celsius
Trial 2 = Hydrochloric acid is dilute. Marble is lump and the temperature is 40 degrees Celsius.
Trial 3 = Hydrochloric acid is concentrated. Marble is lump and the temperature is 20 degrees Celsius

Answer 3

I disagree. The conditions are there. The results are (and I missed them) in the preamble saying they are listed from fastest to slowest. Therefore, the first one listed dissolved the quickest and the last one listed took the longest.

Go through this logically.
I would do this.
Trials 1&2. both dil acid. surface area higher in 1 than 2. T lower in 1 BUT #1 dissolves fastest. So surface area (finely ground) is most important

Trials 2 & 3. Surface area is not a factor since both are lumps. Acid is stronger in 3 and T is lower in 3 BUT 2 is faster than 3; therefore, temperature must be the second most important which leaves concn as the least important.
Do you agree?

Answer 4

Thanks so much I agree:)
