How can the rate of a reaction involving gaseous molecules be increased?
If the pressure of a reacting gas is increased:the reactant particles are closer togetherthe frequency of collisions between reactant particles increasestherefore the rate of reaction increasesIf the temperature of a reacting gas is increased:the particles can collide more often and with more energytherefore the rate of reaction increasesIf a catalyst is used:the activation energy is loweredmore particles have enough energy to reacttherefore the rate of reaction increases
