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
It is acting as a biological catalyst.
The molecule's function and chemical and physical properties
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
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.

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.
To make a serving tray with handles, you can follow these steps: Choose a sturdy material like wood or metal for the tray base. Cut the material to your desired size and shape for the tray. Attach handles to the sides of the tray using screws or glue. Sand the edges and surface of the tray for a smooth finish. Optionally, you can paint or stain the tray for a decorative touch. Let the tray dry completely before using it to serve food or drinks.
To create a DIY plastic tray at home, you can use a plastic container or sheet, cut it to the desired size and shape, and then decorate or customize it as you like. You can also add handles or feet to the tray for functionality.
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.
