Catalyst Ea (kJ/mol)
Tungsten 163
Osmium 197
The better catalyst would be
because
the activation energy

Transcribed Image Text:Hydrogen peroxide can be decomposed according to the following equation:
2H₂O2(1)→ 2H₂O(l) + O2(9)
A student performed four trials to test the result of how much oxygen was produced by changing variables. In each trial, the amount of hydrogen peroxide decomposed was a controlled variable. The students results are displayed in the following graph:
