Answer:
The answer to your question is: B it will shift towards the endothermic reaction
Step-by-step explanation:
A. It will shift towards the products. A reaction normally shifts towards the products but we need to consider if it is an endothermic or an exothermic reaction, then this option is incomplete.
B. It will shift towards the endothermic reaction. This option is correct, because endothermic reactions needs heat to happen. This is the right answer.
C. It will not change. It is a reversible reaction and it will shift according to the factors so there will be a change, this option is not right.
D. It will shift towards the exothermic reaction. An exothermic reactions releases heat, it does not need heat, so this option is incorrect.
