Input (English): Question: According to the Arrhenius equation (k = A e-Ea / RT): 
 Options:  <0> The speed of a reaction is directly proportional to the temperature. <1> A high activation energy implies that the speed constant depends markedly on the temperature. <2> The pre-exponential factor or frequency factor (A) is dimensionless. <3> The activation energy depends on the temperature. <4> The activation energy is always negative.
Output (English): pharmacology
