Temperature in centigrade is zero.

B

The absolute temperature is zero.

C

The absolute temperature is infinity.

D

No suitable answer.

Text Solution

Verified by Experts

The correct Answer is:
C
`k = Ae^(-E_(a)//RT)`
(`A` is called pre-exponential factor)
When `T rarr oo`
`k = Ae^(-E_(a)//R_(oo))`
`k = Ae^(0)[(-E_(a))/(R xx oo)=0]`
`:. K = A`

The rate constant for the decompoistion of a certain reaction is described by the equation: log k(s^(-1)) = 14 - (1.25 xx 10^(4) K)/(T) At what temperature, rate constant is equal to pre-exponential factor?

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).
