Rate Calculations and Yields

On the other hand, the hydrogen generation rate is reported as volume generated per unit area such as mL min cm when a substrate in foam form is used [21,41,45,46,60]. 

Alternatively hydrogen generation rate is expressed as moles of generated hydrogen per unit time such as mol min [37,61] or mmol mim [35]
