About Equilibrium Constant K — atp hydrolysis
Calculate the equilibrium constant K for atp hydrolysis from the standard free-energy change. K = exp(−ΔG°/RT). The calculation uses K = exp(−ΔG°/RT). Why it matters: Whether a reaction is spontaneous, how fast it goes, and how its equilibrium shifts with temperature all flow from a handful of equations. Sign and unit errors here are notoriously easy to make. K > 1 favours products; K < 1 favours reactants. Before you trust the number, double-check: mixing J and kJ for ΔH vs ΔS; using °C instead of K; dropping the minus sign in ΔG = ΔH − TΔS. Everything is computed on your own device — nothing you enter is uploaded — so the tool is safe for unpublished sequences, proprietary formulations and sensitive measurements, and easy to cite in a methods section or lab SOP.

Frequently asked questions
Any tips specific to this calculation?+
K > 1 favours products; K < 1 favours reactants. Also watch out for: mixing J and kJ for ΔH vs ΔS and confusing rate constant with equilibrium constant.
Is this equilibrium constant k — atp hydrolysis free to use?+
Yes. It is completely free, needs no sign-up, and runs entirely in your browser — there are no usage limits.
What formula does it use?+
It uses K = exp(−ΔG°/RT) The full worked example is shown beneath the result so you can verify each step.
What are the most common mistakes here?+
In chemical thermodynamics and kinetics, watch for: mixing J and kJ for ΔH vs ΔS; using °C instead of K; dropping the minus sign in ΔG = ΔH − TΔS; confusing rate constant with equilibrium constant. This tool shows the working so you can catch these before they cost an experiment.
Does my data leave my device?+
No. All computation happens locally in your browser. Nothing you enter — sequences, concentrations or measurements — is uploaded to any server, so it is safe for confidential work.
Can I cite this tool?+
Yes — use the “Cite this tool” snippet on the page. Many users link these calculators from methods sections, lab SOPs and teaching materials.
