The chain on a bicycle rusts faster when the bicycle is left outside in damp conditions. Which of the following factors affect the rate at which the bicycle chain rusts?
A. Surface area
B. Concentration of oxygen atoms in air
C. Temperature
D. All of the above
E. B and C
F. A and C
G. A and B
Answer (2)
D
Larger surface area speeds up reactions Rust is an oxide so more oxygen should speed up rate of rust Temperature also speeds up reactions
The humidity affects it aswell
The factors affecting the rate at which a bicycle chain rusts include surface area, concentration of oxygen, and temperature. Together, these contribute to the process of rusting, making the correct answer D. All of the above . Each factor plays a significant role in how quickly rust can develop.
