Sentence completion and line matching

Foundation tier papers may include questions in which you have to complete a sentence, or draw lines to match correct options. These questions will include 'distractors', which are incorrect choices.

Make sure you only use words from the given list. When you answer a line matching question, use straight lines rather than complex wavy lines. Do not draw more lines than necessary to answer the question.

These questions have been written by Bitesize consultants as suggestions to the types of questions that may appear in an exam paper.

Sample question 1 - Foundation

Question

Use words from the list to complete the sentences.

  • rate
  • number
  • energy
  • mass

a) When the concentration increases, the rate of reaction increases because the ______ of collisions increases. [1 mark]

b) When the temperature increases, the frequency of collisions increases and so does the ______ of the collisions. [1 mark]

a) When the concentration increases, the rate of reaction increases because the rate of collisions increases. [1]

b) When the temperature increases, the frequency of collisions increases and so does the energy of the collisions. [1]

Sample question 2 - Foundation

Question
