H6P6: Urbium Oxide
First Part of the Question:
Urbium (Ur) is an upscale element found in big cities. Its oxide (UrO2) is not very stable and decomposes readily at temperatures exceeding 66∘ C. The figure below shows how the rate of reaction varies with the concentration of UrO2 at 75∘ C.
The rate r is in units of M⋅s−1 and the concentration c of UrO2 is in units of M (mole⋅L−1). The slope has a value of 1.34 and the intercept has a value of 1.51. What is the order of reaction for the decomposition of urbium oxide?
Second part of the Question:
Select the graph below that best represents how the rate of reaction varies with concentration of urbium oxide at 100∘ C (red) compared with the rate versus concentration at 75∘ C (black).
second part = B
Any idea for The first part?
