Reactor Conversion (Batch)
Compute a reactant's conversion, X = (C₀ − C)/C₀·100%, the fraction of reactant consumed in the reaction, from the initial (C₀) and final (C) concentrations. Conversion is the fundamental measure of a chemical reaction's progress: 0% means nothing reacted, 100% that the reactant is exhausted. Together with selectivity and yield, it defines a reactor's performance. Enter the initial and final concentrations.

Conversion in a batch reactor
The conversion X = (C₀ − C)/C₀ is the number that tells how much of a chemical reaction has actually happened: the fraction of the reactant that was consumed. X = 0 means nothing reacted; X = 1 (100%) means the reactant was used up completely. It is the most basic measure of reactor performance. But converting is not enough on its own: a run can reach high conversion while making the wrong product (by-products). That is why conversion always travels with two siblings — selectivity (did the reactant go to the desired product?) and yield (conversion × selectivity, how much of the target product was obtained from the reactant charged). There is a classic trade-off here: pushing conversion towards 100% (more time, more temperature) usually lowers selectivity, favouring side reactions and product degradation. For that reason many processes deliberately run at partial conversion and recycle the unconverted reactant back to the reactor. Enter the initial and final concentrations.

Zeldovich Number
Computes the Zeldovich number of a flame, β = E_a·(T_b − T_u) ÷ (R·T_b²), the activation energy made dimensionless by the temperature rise across the flame front. It measures how sensitive the reaction rate is to a small temperature change: a high β (typically 8 to 12 for hydrocarbons) means the reaction is concentrated in a very thin layer near the flame temperature, which justifies the large-activation-energy assumption of asymptotic flame theory and the extinction and cellular-instability criteria. The universal gas constant R = 8.314 J/(mol·K) is adopted, with activation energy in J/mol and temperatures in kelvin. Enter the activation energy, the burned gas temperature and the unburned gas temperature.
Equilibrium Constant from Conversion
Compute the equilibrium constant of a simple A ⇌ B reaction from the equilibrium conversion, Keq = X/(1 − X), where X is the fraction of reactant converted when the reaction reaches equilibrium. It shows the direct relation between how far a reaction 'goes' and its Keq: high conversions (X→1) imply a large Keq (favorable reaction); X = 0.5 gives Keq = 1 (equilibrium in the middle). Enter the equilibrium conversion (fraction).
