The rate of a chemical reaction increases by 2 times for every 10°C rise in temperature. How many times will the rate increase if the temperature is raised from 20°C to 70°C?
- 10
- 16
- 32
- 64
📝 Detailed explanation
Using Van't Hoff rule: v₂/v₁ = γ^((T₂-T₁)/10).γ = 2, ΔT = 70 - 20 = 50.
Increase = 2^(50/10) = 2⁵ = 32.
