can k be negative in rate law?

Another way to think of it is that reactions rates are always positive and since k is a proportionality constant that relates some given concentration(s) (which are always positive) with the rate (also always positive), it's not possible for k to be negative.

If K is less than 1, the mixture contains mostly reactants. If K is about equal to 1, the reaction will reach equilibrium as an intermediate mixture, meaning the amounts of products and reactants will be about the same.

We compare Q and K to determine which direction the reaction will proceed to obtain equilibrium. If Q is greater than K, the system will shift to the left. If Q is less than K, the system will shift to the right. If Q is equal to K than the system is already at equilibrium so it will not shift in either direction.

If there is an absolute value of a negative number (l-6l), the distance of it away from zero cannot be a negative distance. So if the distance is always positive, then the absolute value will always be positive.

Cpk can only have positive values. It will equal zero when the actual process average matches or falls outside one of the specification limits. The Cpk index can never be greater than the Cp, only equal to it. This happens when the actual process average falls in the middle of the specification limits.

1) Equilibrium can be approached from either direction. 2) Kc does not depend on the initial concentrations of reactants and products. 3) Kc does depend on temperature. ⇒ If the Kc value is large (Kc >> 1), the equilibrium lies to the right and the reaction mixture contains mostly products.

Why is the KL divergence always non-negative? An important property of the KL divergence is that it's always non-negative, i.e. DKL(P || Q) ≥ 0 for any valid P, Q.

When you subtract two negative integers and the first integer (or minuend) is smaller than the second integer (or subtrahend), the difference is negative. When you subtract two negative integers and the first integer (or minuend) is larger than the second integer (or subtrahend), the difference is positive.

There is a bit of contention as to whether or not an IS-LM model can intersect at negative interest rates. This has to do with the elasticity of the the LM curve at low levels of Output. ... Much of this has to do with the market sentiment and conditions upon which the central bank chooses to target negative rates.

Adding a thumb rule to all the answers above: negative number modulo k = k minus positive number modulo k. To find (−n)%k just find k−(n%k). Ex: (−144)%5=5−(144%5)=5−(4)=1.

Implies that the law of diminishing marginal utility cannot be applied to goods, such as television and refrigerator. This is because the consumption of these goods is not continuous in nature.

Rate laws or rate equations are mathematical expressions that describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In general, a rate law (or differential rate law, as it is sometimes called) takes this form: rate=k[A]m[B]n[C]p…

Negative real interest rates If there is a negative real interest rate, it means that the inflation rate is greater than the nominal interest rate. If the Federal funds rate is 2% and the inflation rate is 10%, then the borrower would gain 7.27% of every dollar borrowed per year.
