L think the answer is kc=:02:-3
An increase in the frequency of effective collisions because it is these collisions that cause reactants to change to products
SO2 is not likely to be ionic.
An ionic bond is most commonly formed between a metal and a non-metal.
K (potassium) and Br (bromine) are a metal and non-metal pair.
Al (aluminum) and Cl (chlorine) are a metal and non-metal pair.
S (sulfur) and O (oxygen) are both non-metals, and likely formed a covalent bond instead of an ionic bond, which is common for two non-metals.
