For the given reaction, Deltan(g)=2-(3)=-1 :. DeltaH^(Θ)=DeltaU^(Θ)+Deltan(g)RT =-10.5 kJ+(-1)(8.314xx10^(-3)kJ)(298) =-10.5-2.48=-12.98 kJ DeltaG^(Θ)=DeltaH^(Θ)-T DeltaS^(Θ)=-12.98 kJ-298 (-44.1xx10^(-3)k J) =-12.98 kJ+13.14 kJ=0.16 kJ
Question: for a reaction 2a+2b=c+d where doubling the concentration of reactant A doubles the rate, while doubling reactant b quadruples the rate, what is the overalll order of the reaction for a reaction 2a+2b=c+d where doubling the ...

Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain within seconds. Here, we found that cholecy...
