Please tell me which one is correct a,b,c or d need it for studying 16. For the following endothermic reaction at equilibrium:2SO3(g) S 2SO2(g) + O2(g)which of the following will increase the value of K?Removing SO3(g) (at constant T)B Adding SO2(g) (at constant T)Adding a catalyst (at constant T)Increasing the temperature

1- When equilibrium constant ( K ) less than one then equilibrium shifted towards reactant side. And if equilibrium constant ( K ) more than one then equilibrium shifted towards products side. Increasing the value of K means reaction equilibrium moving towards forward direction. 1- Removing SO3 and adding SO2 then equilibrium shifted towards backward direction because more and more SO2 molecules converted into more and more SO3 so these two are not correct for increasing value of K 2- When you added a catalyst on a equilibrium reaction then rate of forward and backward increasing with same amount so that equilibrium constant ( K ) will remain same so there is no effect on equilibrium. 3- This reaction is endothermic in forward direction. When you increasing the temperature then equilibrium shifted towards endothermic side means here in products side. That means it's produces more and more products at high temperature. So it's increases the value of K because increasing temperature reaction moving products side. Hence, the correct answer is : D) Increasing the temperature
