Which process accelerates formaldehyde production from methanol using a silver catalyst at high temperature?

A)Increased methanol adsorption on silver
B)Desorption of byproducts from silver
C)Formation of silver oxide inhibiting sites
D)Exothermic decomposition of formaldehyde

💡 Explanation

When temperature rises, methanol adsorption increases, enhancing the collision frequency and surface reaction on the supported silver catalyst, thus accelerating formaldehyde production. Therefore increased methanol adsorption results, rather than byproduct desorption, oxide formation, or formaldehyde decomposition which have opposing effects.
