Increasing temperature increases the number of collisions and the potential energy of the colliding molecules anddecreases the reaction rate.
True or False PLZ HELP!!

Answers

Increasing temperature does increase the amount of collision but it increases the kinetic energy of the molecules not the potential energy. Potential energy brings molecules together or apart (depending) and kinetic energy makes the molecules move around or not. Hope this helps

The type of bond between atoms of potassium and chloride in a crystal of potassium chloride a. hydrogen bond
b. ionic bond
c. polar covalent bond
d. pure covalent bond
e. metallic bond

Answers

It's an ionic bond because potassium is a metal and chlorine is a non-metal so the potassium donates an electron to the chlorine and so the potassium becomes a positive ion and the chlorine becomes a negative chloride ion. Opposite ion charges attract so an ionic lattice is formed.
