Re: Units of K. Postby Rachel Wile 2D » Tue Feb 21, 2017 7:18 am. For a zero order, the units of k are M/s, or mol*L^-1*s^-1. For first order, the units are 1/s or s^-1. For second order, the units are 1/M*s or L*mol^-1*s^-1. You will notice that there is a pattern here.

Q. Q Q. Q. can be used to determine if a reaction is at equilibrium, to calculate concentrations at equilibrium, and to estimate whether a reaction favors products or reactants at equilibrium. As a system approaches towards equilibrium, Q approaches towards K. 3) The reaction will proceed to the right. 4) No, it is not at equilibrium. Since Q
This equilibrium constant is a quantitative measure of the strength of an acid in a solution. K a is commonly expressed in units of mol/L. This chemistry video tutorial explains how to determine the units of the rate constant K for a first order reaction, second order reaction, and a zero order
The kelvin (K) is the unit of the thermodynamic temperature scale. This scale starts at 0 K. The incremental size of the kelvin is the same as that of the degree on the Celsius (also called centigrade) scale. 2019-10-04 · Unit conversions only work if the units are the same type.

The numerical value of K depends on the particular reaction, the temperature, and the units used to describe concentration. For liquid solutions, the concentrations are usually expressed as molarity. For a mixture of gases, the concentration of each molecular species is commonly given either as molarity or as pressure in atmospheres.
