What is true if ln K is negative? ΔGorxn is positive and the reaction is spontaneous in the reverse direction.

Is Ln K supposed to be negative?

Re: If slope for ln(A) vs. t is negative is k? Rate constants (k) are always positive. Rates can be negative or positive depending on whether it’s for formation or decomposition.

What is true if ln k is negative ΔG RXN is positive and the reaction is spontaneous in the reverse direction?

Answer: ΔG°rxn is positive and the reaction is spontaneous in the reverse direction.

What does it mean when K is negative?

When this is negative, the reaction is spontaneous, therefore k is greater than one because more product is produced.

What does a negative concentration mean?

• Why are there negative concentration values in the data? What do they mean? A negative concentration value indicates that the sample was analyzed but that the concentration was below the determination limits of the analytical method.

Can the concentration be negative?

It is not possible for concentration values to be negative.

Can values be negative?

While positive ethic value generally correlates with something that is pursued or maximized, negative ethic value correlates with something that is avoided or minimized. Negative value may be both intrinsic negative value and/or instrumental negative value.

Can absorbance be negative?

A “negative absorbance” means your reference is absorbing more than your sample. You have a “zero error”. You can correct this by displacing your zero reference.

Can molarity be negative?

It is impossible to have a negative amount of moles. It is also impossible to have a negative mass of solvent. Therefore, it is impossible to have a negative molality.

Can molal concentration be negative?

ΔTf=−iKfm , where, ΔTf=Tf−T*f is the final freezing point (solution) minus the initial freezing point (solvent), and is always negative. m is the molal concentration of the solution. ( molality = moles of solute / kg of solvent.)

Can you have a molarity over 1?

Yes. As molality = no of moles of solute/ weight of solvet in kg. If no of mole is greater than 1 in 1kg of solvent then molality is grater than 1.
