A technician adds metal R to a solution of T sulfate and metal T to a solution of R sulfate. The results are shown.
| Test | Result |
|---|---|
| R added to T sulfate solution | T forms on the surface of R |
| T added to R sulfate solution | No reaction |
Both metals react with dilute hydrochloric acid. The technician plans to compare R and T in dilute hydrochloric acid using equal masses with the same surface area, acid volume and concentration, and temperature.
Explain what the results show about the relative reactivities of R and T, and predict which metal would produce hydrogen faster in the acid comparison.
