The rate constant of a reaction increases linearly with increase in temperature.

The rate of reaction increases isgnificantly with increase in temperature. Generally, rate of reactions are doubled for every 10^(@)C rise in temperature. Temperature coefficient gives us an idea about the change in the rate of a reaction for every 10^(@)C change in temperature. "Temperature coefficient" (mu) = ("Rate constant of" (T + 10)^(@)C)/("Rate constant at" T^(@)C) Arrhenius gave an equation which describes aret constant k as a function of temperature k = Ae^(-E_(a)//RT) where k is the rate constant, A is the frequency factor or pre-exponential factor, E_(a) is the activation energy, T is the temperature in kelvin, R is the universal gas constant. Equation when expressed in logarithmic form becomes log k = log A - (E_(a))/(2.303 RT) Activation energies of two reaction are E_(a) and E_(a)' with E_(a) gt E'_(a) . If the temperature of the reacting systems is increased form T_(1) to T_(2) ( k' is rate constant at higher temperature).

The rate of an exothermic reactions increases with increase in temperature.

 Why does the rate of a reaction increase with rise in temperature?

The rate of reaction increases by the increase of temperature because

Assertion : Rate of reaction increases with increase in temperature. Reason : Number of effective collisions increases with increase in temperature.

Assertion (A) : The value of K for a reaction may increase or decrease with increase in temperature depending upon whether the reaction is exothermic or endothermic. Reason (R) : With increase in temperature, the extent of reaction increases.

In which reaction the equilibrium constant value increases with increase in temperature ?
