What is meant by rate of reaction?
Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.
How do you determine the rate of a reaction?
Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.
What are the 4 rates of reaction?
We might not always notice them but there are four indicators that show a chemical reaction has taken place:
- colour change.
- effervescence.
- precipitation.
- energy (temperature) change.
What is rate of reaction Class 12?
Rate of a chemical reaction IS the change in the concentration of any one of the reactants or products per unit time. It is expressed in mol L-1 s-1 or Ms-1 or atm time-1 units. Rate of reaction. = (decrease/increase in the concentration of reactant/product/time taken)
