How are chemical reaction rates measured?

By tracking reactant usage or product formation speed.

What equation is used to calculate reaction rates?

Rate = quantity of reactants used / time taken.

Graphs show reactant mass decrease and product volume increase.

Rates can be expressed in moles per minute.

If 180 cm cubed of hydrogen is produced in 2 minutes, the rate would be 1.5 cm cubed per second.

Chemical reactions can occur at different speeds, ranging from slow processes like rusting to rapid reactions such as explosions. The rate of a reaction is quantified by monitoring how fast reactants are consumed or products are generated, often measured in grams or cubic centimeters per second.
Calculating reaction rates involves dividing the amount of reactants used or products formed by the time taken, expressed as a ratio such as reactant quantity per time unit. Graphs can visually depict these changes, showing reactant mass decreasing rapidly then stabilizing, while product volume rises quickly before reaching a plateau. Rates can be denoted in alternative units like moles per minute, determined by dividing the quantity by the time elapsed.

Chemical reactions have varying rates, from slow reactions like rusting of iron to fast reactions like explosions. The rate of reaction can be measured by tracking how quickly reactants are used up or products are formed, with rates expressed in grams or cm cubed per second.
To calculate the rate of reaction, one can use the equation rate = quantity of reactants used / time taken or rate = quantity of products formed / time taken, with time measured in seconds. For example, if 180 cm cubed of hydrogen is produced in 2 minutes, the rate would be 1.5 cm cubed per second.
Graphs can illustrate how reaction rates change over time, with reactant mass decreasing rapidly at first then slowing down, while product volume increases quickly initially then levels off. Rates can be expressed in various units like moles per minute, calculated by dividing the quantity by the time taken.
