WebMay 8, 2024 · ΔH is positive and ΔS is negative. This condition describes an endothermic process that involves a decrease in system entropy. In this case, Δ G will be positive … Webpositive G: [noun] the G force exerted on the human body in a headward direction during acceleration.
WebTo put it simply, If g opposes the motion of the object (eg. : rock thrown upwards, g tries to pull it back to the surface) then you take the acceleration as "-g" / negative. If g helps your motion, then its positive. (a rock falling from a roof, g helps it go in the direction it is intented to go in aka downwards). Webln x will be negative if x is between 0 and 1. You can have concentrations ranging from 0 to 1 in any unit you like (e.g. 0.5 mol/L), so yes, ln [conc] can be negative. The same goes for k and ln k As a good reminder, though, you can never take a log of something with unit.
Web3 Answers Sorted by: 4 First off, we require k < 0 then we require that f has no roots so that it is always negative. That is, we need its discriminant to be < 0. i.e: 4 − 4 k 2 < 0 1 − k 2 < 0 k 2 > 1 since we know that k < 0 then this becomes k < − 1.
