Homework Answers
Answer: c) equilibrium.
A) rate law : rate law or rate equation for achemical reaction is an equation that combines the reaction rate with concentrations or pressures of reactants and constant parameters .
Rate= K [A]^x.
B)rate constant:
Rate constant may be defined as the rate of the reaction when the concentration of each reactant is taken as unity.
C. Equlibrium:
The concentration of reactants and concentration of products reaches a constant level ,that level called as equilibrium.
D.elementary process:
Each step of the reaction mechanism is known as an elementary process.
E. Reversible reaction:
The reaction can proceed in both forward and backward is called reversible reaction .

In order for a reaction to reach equilibrium, there must be reversible steps between the reactants and the products. A classical reversible reaction is the phosgene reaction. The proposed mechanism has three reversible steps: Derive the rate law for this reaction in the steady state approximation. When the rate law is obtained. Examine it under conditions of equilibrium (rate = 0). Observe the relationship between the rate constants and another obvious quantity.

At equilibrium, the concentrations of reactants and products can be predicted using the equilibrium constant, Kc, which is a mathematical expression based on the chemical equation. For example, in the reaction aA+bB?cC+dD where a, b, c, and d are the stoichiometric coefficients, the equilibrium constant is Kc=[C]c[D]d[A]a[B]b where [A], [B], [C], and [D] are the equilibrium concentrations. If the reaction is not at equilibrium, the quantity can still be calculated, but it is called the reaction quotient, Qc, instead of...
