A catalyst does not affect the value of Kc

• True

• False

• True

• False

What is the normal unit used for enthalpy

• kJ

• J

• kJ mol^-1

• J mol^-1

Increasing the pressure will increase the rate of a reaction because

• there are less gas particles to collide

• there are more gas particles to collide

• increasing the pressure acts a catalyst

• I have no idea really
