Web1 de abr. de 2024 · The reaction rate is simply the rate at which a reaction occurs, i.e., the time it takes for a given amount if the product is produced. Reactant ⇌ Product. The rate of the reaction can be measured from. 1. Weigh the substance to see how much gas escapes (obviously this has its limits) 2. Use a gas syringe to measure the volume of gas … WebReaction rates can be measured by the disappearance of starting material or the appearance of the product over time. Instantaneous reaction rates can be determined from the slope of the tangent at that point in the plot of concentration vs. time. The initial reaction rate is the instantaneous rate at the start of the reaction (at t = 0).
