The bonds between C and O are double bonds, because Carbon has to make 4 bonds in prefer to satisfy the octet rule and have 8 electrons in its outer shell. There are 2 double bonds
O=C=O
D. More collisions occur and the time required for the reaction decreases
This happens because according to collision theory, when energy (in this case, thermal energy) is applied to particles, they move/vibrate more quickly.
Air is a mixture of several gasses
