Rate of Chemical Reaction Solution

Follow our step by step solution on how to calculate Rate of Chemical Reaction?

FIRST Step Consider the formula

r = \frac{Δc}{Δt}

Next Step Substitute values of Variables

∴

r = \frac{50mol/L}{5s}

Next Step Convert Units

∴

r = \frac{50000mol/m³}{5s}

Next Step Prepare to Evaluate

∴

r = \frac{50000}{5}

Next Step Evaluate

∴

r = 10000mol/m³*s

LAST Step Convert to Output's Unit

∴

r = 10mol/L*s

Variables

Rate of chemical reaction

The Rate of chemical reaction is the rate change of concentration of any one of the reactants or products per unit of time.

Symbol: r

Measurement: Reaction RateUnit: mol/L*s

Note: Value can be positive or negative.

Formulas to find Rate of chemical reaction

Change in concentration

The Change in concentration is defined when there is a decrease in the concentration of reactant and an increase in the concentration of the product as the reaction proceeds.

Symbol: Δc

Measurement: Molar ConcentrationUnit: mol/L

Note: Value can be positive or negative.

Formulas to find Change in concentration

Total time interval

The Total time interval is the amount of time required for the total change in concentration.

Symbol: Δt

Measurement: TimeUnit: s

Note: Value can be positive or negative.
