URGENT QUESTION 2)

???????

The following molecule has an enantiomer: Which two of the following are not drawings of the enantiomer of this molecule? 1. 2. 3. 4. 2 and 4 2 and 3 1 and 4 1 and 3 3 and 4 1 and 2 Which of the following statements is true? Catalysed and uncatalysed reactions occur by the same mechanism. A reaction will take place when two molecules collide with combined kinetic energy greater than the activation energy. Reaction rates of first order reactions increase with increasing concentration of reactants because there are more collisions between reactant molecules Reactions decrease in rate as the reaction temperature decreases because activation energies are lower at lower temperatures.
