For this question, it is important that you notice the differences between the two lines, P & Q. The two differences are the height which the reaction reaches (i.e. the maximum product produced), and the rate at which the reaction proceeds.
Moving from P to Q the rate has reduced. This would suggest that changes in variables which slow reactions would lead to the change. You can find more on factors affecting the rate of reaction here. This consideration is sufficient to answer the question, however, you should also ponder that the lower maximum volume of CO2 is also explained by the correct choice. |

Unit 1_4 Homework Question 1 (MCQ) Help Card
Ions form when electrons are completely lost or gained by atoms. Pauling devised the comncept of ionic character in which a bond with 100% ionic character has no sharing of electrons and a bond with 0% ioninc character would have electrons equally shared. The degree to which sharing can occur is determined by the relative electronegativity of the atoms involved in the bond.
