Estimate the rate of the reaction, H^+(a q)+OH^-(a q) ⟶H2 O...

Estimate the rate of the reaction, $$ \mathrm{H}^{+}(a q)+\mathrm{OH}^{-}(a q) \longrightarrow \mathrm{H}_{2} \mathrm{O} $$ given the rate law for the reaction is$$\text { rate }=\left(1.3 \times 10^{11} \mathrm{~L} \mathrm{~mol}^{-1} \mathrm{~s}^{-1}\right)\left[\mathrm{OH}^{-}\right]\left[\mathrm{H}^{+}\right]$$ for neutral water, where $\left[\mathrm{H}^{+}\right]=1.0 \times 10^{-7} M$ and $\left[\mathrm{OH}^{-}\right]=1.0 \times 10^{-7} M$

Key Concepts

Reaction Order

Reaction order is defined by the power to which a reactant's concentration is raised in the rate law. Each term's exponent signifies the order with regard to that particular reactant, and the sum of these exponents gives the overall order of the reaction. This indicates the sensitivity of the reaction rate to changes in reactant concentrations.

Reaction Rate

The reaction rate describes the speed at which reactants are converted into products over time. It is calculated using the rate law and provides essential insights into the kinetics of a reaction. Understanding the reaction rate is key to controlling and optimizing chemical processes, ensuring efficiency and effectiveness in various applications.

Rate Law

The rate law is a mathematical expression that shows how the rate of a chemical reaction depends on the concentration of its reactants. It is fundamental in chemical kinetics because it links the speed of a reaction to the amounts of substances present and defines the relationship via specific exponents that indicate the order with respect to each reactant.

Rate Constant

The rate constant, often denoted by k, is a proportionality factor in the rate law that reflects the intrinsic rate of the reaction under given conditions such as temperature. It quantifies how rapidly a reaction proceeds when reactant concentrations are fixed, providing a measure that allows comparisons between different reactions or under varying conditions.
