Correct answer is (d) N +1 / 2 O 2 arrow NO

Q. Which of the following is an endothermic reaction?

$3 H_{2} + N_{2} \to 2 N H_{3}$

$C + O_{2} \to C O_{2}$

$PC l_{3} + C l_{2} \to PC l_{5}$

$N + 1/2 O_{2} \to NO$

Correct answer is (d) $N + 1/2 O_{2} \to NO$

Q. Which of the following is an endothermic reaction?

3H2​+N2​→2NH3​

C+O2​→CO2​

PCl3​+Cl2​→PCl5​

N+1/2O2​→NO

Correct answer is (d) N+1/2O2​→NO

$3 H_{2} + N_{2} \to 2 N H_{3}$
