Change in volume of the system does not alter the number of moles in which of the following equilibr — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

Let us consider the change in moles of given reactions as follows- In option A, number of moles of product – reactant= 2- 2= 0 In option B, number of moles of product – reactant= 2- 1=1 In option C, number of moles of product – reactant= 2- 4=-2 In option D, number of moles of product – reactant= 2- 1=1 Clearly in option A, the number of moles on both reactant and product side are same. Therefore, any change in volume doesn’t affect it.
