Ex Input:
Question: The Arrhenius equation: 
 Options:  <1> It relates the speed of a chemical reaction with the so-called constant velocity and with the concentrations of the reactants raised to their stoichiometric coefficients. <2> It relates the constant of speed of a chemical reaction with the energy of activation of said reaction, so that if the energy, of activation is high the reaction is fast. <3> It is only fulfilled for unimolecular reactions. <4> It relates the speed constant to the temperature through the activation energy and the pre-exponential factor. <5> It allows to obtain the activation energy of an elementary reaction by only representing the decimal logarithm of the temperature versus the inverse of the reaction time.

Ex Output:
4
