If the number of moles decreases from 5 moles of gaseous reactants to 2 moles of gaseous product, the overall change in volume of the system is negative.
<h3>What is volume?</h3>
Volume refers to the space occupied by an object. Gases do not have a specific volume, rather they take on the volume of the container. We must note that the volume of given mass of gas is directly proportional to the number of moles present.
Hence, if the number of moles decreases from 5 moles of gaseous reactants to 2 moles of gaseous product, the overall change in volume of the system is negative.
