Temperature and Rate

Part of the Energy, Rates and Equilibrium section of Coddy's Chemistry journey. Lesson 17 of 35.

Hotter particles collide more often, and many more collisions reach E_a.

Rule of thumb: the rate about doubles for every 10 K. 20 K warmer: about 4 times faster.

A fridge slows the reactions that spoil food.

Challenge

A reaction in a test tube gives gas at $3\ \mathrm{mL/min}$ . The tube is warmed by $20\ \mathrm{K}$ . If the rate doubles every 10 K, what is the new rate r_2?

Try it yourself

Solve for $r_{2}$

Test yourself
