Description: In the combustion of hexane (a low-boiling component of gasoline),2 C6 H14(g)+19 O2(g) ⟶12 CO2(g)+14 H2 O(g) it was found that the rate of decrease of C6 H14 was 1.20 mol L^-1 s^-1 (a) What was the rate of reaction with respect to O2 ? (b) What was the rate of formation of CO2 ? (c) What was the rate of formation of H2 O ?

step 1 So here we're given an example of a specific reaction where hexane reacts with oxygen to form ca

Step 1

20 \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}$. We express this with a negative sign because the concentration of $\mathrm{C}_{6} \mathrm{H}_{14}$ decreases over the course of the reaction. So, we can write this as: $$-\frac{\Delta[\mathrm{C}_{6} Show more…

Key Concepts

Stoichiometric Relationships

Balanced chemical equations provide stoichiometric coefficients that relate the rates of consumption of reactants and formation of products. These coefficients are used to convert a given rate of change for one species into the corresponding rates for other species involved in the reaction.

Reaction Rate Units

The rate of a reaction is typically expressed in units of moles per liter per second (mol L?¹ s?¹), which standardizes the way changes in concentration are measured over time, allowing for consistent comparison of reaction speeds.

Rate of Reaction

This concept describes how quickly a reactant is consumed or a product is formed in a chemical reaction. It is defined as the change in concentration per unit time and provides a measure of the speed of the reaction.
