Question

Statement (A): Increase in temperature favours the endothermic reaction

Statement (B): Decrease in temperature favours the exothermic reaction

Statement (C): There is no effect of pressure on equilibrium if the number of moles of gaseous reactants and products are different.

• A. All the statements are correct
• B. All the statements are incorrect
• C. A, B are correct and C is incorrect
• D. A, B are incorrect and C is correct

Answer 1

Answer: (C)

A, B are correct and C is incorrect

$A\to$ system must be closed otherwise upwards will exape and equation will never be reached

$B\to \Delta H>0$ for the reaction

$\therefore$ High temperature prefers

$C\to \Delta H>0\therefore$ Low temperature takes reaction backward
