List of top Chemistry Questions on Temperature Dependence of the Rate of a Reaction

Given below is an expression for the rate constant of a first order reaction occurring at a certain temperature \(T(K)\): \[ \ln k = 14.34-\frac{1.25\times10^4}{T} \] Given \(R=1.987\text{ cal mol}^{-1}\text{K}^{-1}\). The activation energy of the reaction is:

The conversion of molecule X to Y follows second-order kinetics. If the concentration of X is increased 3 times, how will it affect the rate of formation of Y? 

What is the effect of temperature on the rate constant of a reaction? 

What is the activation energy for a reaction if its rate doubles when the temperature is raised from 20°C to 35°C ? (R = 8.314 J mol-1 K-1)
