An arrow that points in both directions in a chemical equation is showing that the reaction is reversible and can proceed in both directions. This means that the reactants on the left hand side are also the products of those on the right and vice versa.Know More
It is incorrect to write out a reversible reaction as two separate chemical equations (one for each direction) because the products always react and revert back into the original reactants. Because both reactions happen simultaneously, the chemical system is in a state of flux until equilibrium is reached. This means that there is a point where the concentration of each reactant remains constant and exhibits no net change over time. This does not mean that every reactant is present in equal proportions, though.
The rate of reaction and reaction coefficients of each reactant determines how much of it is produced and how quickly. Because some reactions are faster and require larger amounts of one reactant than another, they are not present in even amounts when the system reaches equilibrium. In dynamic equilibrium systems, the rates of reaction for both sides of the equation are exactly the same, so the concentrations of the reactants and products remain constant even though both reactions continue to proceed indefinitely.Learn more about Chemical Equations
If a reaction is run at a constant temperature, T, the equation is delta G equals delta H minus T times delta S. This is the measurement of whether a chemical reaction is likely to occur with no additional energy input.Full Answer >
Stoichiometry is a branch of chemistry that deals with the relationship between reactants and products involved in a chemical reaction. In other words, it deals with calculations of masses or volumes of relative quantities of elements involved in a chemical reaction.Full Answer >
The balanced equation for the reaction between HNO3 and KOH is written as HNO3 + KOH = H2O + KNO3. HNO3 is the chemical formula representing nitric acid, KOH is the formula representing potassium hydroxide, H2O is the formula for water and KNO3 is the formula for potassium nitrate.Full Answer >
The scientific equation C6H12O6 + 6O2 —> 6CO2 + 6H2O + Energy is the chemical reaction for respiration within a cell. Respiration is defined as the oxidation of sugar by organisms. It occurs in plants and animals and, in most cases, releases energy that is required for other processes in the cell.Full Answer >
