Dependence of Rate of Reaction on Temperature Chemistry Notes
Dependence of Rate of Reaction on Temperature :
→ We know that the rate of chemical reaction increases rapidly with the increase in temperature. So, we determine the rate of a reaction at constant temperature. If temperature changes then order of reaction remains same but the value of rate constant changes.
→ It is found that, “rate constant increases approximately twice with the increase in 10°C rise in temperature in a chemical reaction.” So, the ratio of rate constants at the difference of 10 K temperature is called temperature coefficient.
→ The rate of chemical reaction also increases with increase in temperature because the number of collisions per second between molecules increases with the increase in temperature as a result the rate of reaction also increases. So, Rate of reaction Number of collisions
