b) fertiliser
c) explosive production
d) soap production

• a and b
• b, c and d
• a, b and c
• c and d

Nitrogen + hydrogen −> ammonia is exothermic .  What will happen if we increase the temperature

• The reaction will slow down
• There will be no change in ammonia production
• More ammonia will be produced
• Less ammonia will be produced
