MCQ
In which of the following reaction, the value of ${K_p}$ will be equal to ${K_c}$
  • ✓
    ${H_2} + {I_2}$ $ \rightleftharpoons $ $2HI$
  • B
    $PC{l_5}$ $ \rightleftharpoons $ $PC{l_3} + C{l_2}$
  • C
    $2N{H_3}$ $ \rightleftharpoons $ ${N_2} + 3{H_2}$
  • D
    $2S{O_2} + {O_2}$ $ \rightleftharpoons $ $2S{O_3}$
✓

Answer

Correct option: A.
${H_2} + {I_2}$ $ \rightleftharpoons $ $2HI$
(a) ${n_p} = {n_r}$ then ${K_p} = {K_c}$

where ${n_p}$ $=$ no. of moles of product

${n_r}$ $=$ no. of moles of reactant.
