Assertion (A) : Decomposition reactions are generally endothermic reactions. Reason (R) : Decomposition of organic matter into compost is an exothermic process.
What does one mean by exothermic and endothermic reactions? Give examples.
The diagram below shows the set-up in which electrolysis of water takes place.
Perform the following activity. Take four beakers and label them as A, B, C and D. Put 25 mL of water in A, B and C beakers and copper sulphate solution in beaker D. Measure and record the temperature of each liquid contained in the beakers above. Add two spatulas of potassium sulphate, ammonium nitrate, anhydrous copper sulphate and fine iron fillings to beakers A, B, C and D respectively and stir. Finally measure and record the temperature of each of the mixture above. Find out which reactions are exothermic and which ones are endothermic in nature.
From the following reactions which one is considered to be endothermic reaction:
Which of the following reactions is an endothermic reaction ?
