The rate constant of a first order reaction at 27^@C is 10–3 min–1. The temperature coefficient of this reaction is 2. What is the rate constant (in min–1) at 17^@C for this reaction :-

The rate of reaction ((dx)/(dt)) varies with nature, physical state and concentration of reactants, temperature, exposure to light and catalyst, whereas rate constant (K) varies with temperature and catalyst only. The rate constant K is given as K=Ae^(-E_(a)//RT) where A is Arrhenius parameter or pre-exponential factor and E_(a) is energy of activation. The minimum energy required for a reaction is called threshold energy and the additional energy required by reactant molecules to attain threshold energy level is called energy of activation. The temperature coefficient of reaction I is 2 and reaction II is 3 . Both have same speed at 25^(@)C and show I order kinetics. The rati of rates of reaction of these two at 75^(@)C is:
