Answer 2

Option (a) - Both Assertion and Reason are True and Reason is the correct explanation of the Assertion.

Is the correct answer.

• Chemical equations can be made more informative:
• By indicating the 'physical states ' of the reactants and products.
• By indicating the 'heat changes ' taking place in the reaction.
• By indicating the 'conditions ' by which the reaction takes place.​
• By adding the name of components which is added when the reaction takes place.
• The chemical equation can be made informative by defining it properly through various means:
• ‘l’ for liquids and ‘g’ for gas, ‘s’ is used for solids, for an aqueous solution, ‘(aq)’ is used.
• By indicating heat changes taking place in the reaction is denoted by arrow marks as well
• An exothermic reaction is indicated by writing +Heat or +Heat energy or +Energy on the product side of the equation.
• An endothermic reaction is indicated by writing +Heat or +Heat energy or +Energy on the reactant side of the equation.
• Here is an example to indicate the conditions under which the reaction takes place.
• E.g. If the reaction takes place in the presence of a catalyst, then the symbol/formula of the catalyst is written above or below the arrow sign.
• Hence, Option (a) - Both Assertion and Reason are True and Reason is the correct explanation of the Assertion is the correct answer.
