Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
The temperature of the system
The molecule's function and chemical and physical properties
It is acting as a biological catalyst.
Putting a tray of water in the freezer allows the water to freeze slowly and evenly, resulting in clear ice without trapped air bubbles. Additionally, the shallow tray shape allows for quicker freezing and easier removal of the ice cubes.
no it doesn't
yes
Enzyme reaction rates are influenced by pH because enzymes have an optimal pH at which they function most effectively. Deviation from this optimal pH can denature the enzyme, rendering it less active or inactive. pH affects the enzyme's shape and charge, which in turn affects its ability to bind to the substrate and catalyze the reaction.

How the concentration of the reactants affects the rate of a reaction

These are called enzymes.
It is a matter of personal preference, or advice of a interior designer, there is no "true standard" as it also depends on the shape of the tray ceiling as well.
The chemical compositon and the chemical bonds affect the shape of molecules..

An outside agent that affects the speed or occurrence of a reaction is called a catalyst. Catalysts work by providing an alternative reaction pathway with lower activation energy, allowing the reaction to happen more quickly. They are not consumed in the reaction and can be used repeatedly.
