The rate of formation is a fundamental concept in chemical kinetics, describing how quickly a product is formed in a chemical reaction over a specific period. It is typically expressed in units of molarity per unit time (e.g., M/s or mol L-1 s-1). To calculate the rate of formation, you need to know the change in the concentration of a product and the time interval over which that change occurs.
function calculateRateOfFormation() {
var initialConcentration = parseFloat(document.getElementById("initialConcentration").value);
var finalConcentration = parseFloat(document.getElementById("finalConcentration").value);
var timeInterval = parseFloat(document.getElementById("timeInterval").value);
var resultElement = document.getElementById("result");
resultElement.innerHTML = ""; // Clear previous results
if (isNaN(initialConcentration) || isNaN(finalConcentration) || isNaN(timeInterval)) {
resultElement.innerHTML = "Please enter valid numbers for all fields.";
return;
}
if (timeInterval <= 0) {
resultElement.innerHTML = "Time interval must be a positive value.";
return;
}
var concentrationChange = finalConcentration – initialConcentration;
var rateOfFormation = concentrationChange / timeInterval;
if (isNaN(rateOfFormation)) {
resultElement.innerHTML = "Calculation resulted in an invalid number. Please check your inputs.";
} else {
resultElement.innerHTML = "
