Which of the following reactions conditions will have Reaction A occur at a FASTER, RATE than Reaction $B($choose all the cases in which $A$ is faster, than $B).($A and $B$ are the SAME reaction, but run under DIFFERENT conditions!$)$

Case #$1$: Reaction A has a higher activation energy than Reaction B$.$

Case #$2$ : Reaction A is run at a higher temperature than Reaction B$.$

Case #$3$ : Reaction A makes use of a catalyst while Reaction B does not.

Case #$4$ : Reaction A has half the amount of reactants as Reaction B$.$
