Temperature and rate

Question 1

An increase in temperature of reactant particles

Answer 1

increases rate of reaction

Question 2

Higher temperature ->

Answer 2

more kinetic energy -> reactant particles move faster -> more frequent collisions -> more of the reactant particles have sufficient activation energy -> more product forms per second -> rate of reaction is higher

Question 3

ERQ - temperature and rate

Answer 3

• As temperature increases the rate of reaction also increases
• Reactant particles gain kinetic energy so move around faster
• Frequency of collisions increases
• More of the reactant particles have
  sufficient activation energy so more product forms per second
• The total quantity of product forms stays the same
• Explain the graph
• Both reactions produce the same quantity of gas overall
