IB Chemistry 2.2.12 (HL) Arrhenius equation Questions
Use Arrhenius plots and temperature data to extract activation energy, calculate gradients, and interpret what the slope tells you about `k`.
How this is tested
- identify ln k vs 1/T as the Arrhenius plot and relate its slope to -Ea/R
- calculate Ea from a slope such as -8900, or find the slope from a stated Ea value
- use rates at two temperatures, e.g. tripling from 25 C to 50 C, to calculate Ea
