PLEASE HELP ASAP I WILL GIVE BRAINLIEST! Consider the reaction pathway graph below.
The rate increases by a factor of 9 when the concentration of A triples. The rate triples when the concentration of B triples. What is the new rate law for the reaction?
A) endothermic because Hrxn=-876.8 kJ
B) endothermic because Hrxn=876.8kJ
C)exothermic because Hrxn= -1099.6kJ
D) exothermic because Hrxn=1099.6kJ
