What is the unit of rate constant (K) for a zero-order reaction?
In a zero-order reaction, the rate constant (K) is measured in units of concentration (mol dm-3) per unit time (s-1), which is 'mol dm-3 s-1'. This indicates that the rate of the reaction is independent of the concentration of reactants.

What is the accurate electron configuration for a copper atom?
Copper's electron configuration is an exception to the typical filling order. It's more stable to have a full 3d subshell (3d10) than having a half-filled 4s subshell (4s1). This results in the configuration [Ar]3d104s1.

What type of chemical reaction is represented by the following equation: 3Cl2 + 6NaOH → NaClO3 + 5NaCl + 3H2O?
Zymase is a complex of enzymes found in yeast that catalyzes the fermentation of sugars, such as glucose, into ethanol and carbon dioxide. This process is fundamental in brewing and baking industries.
