hi everyone for this problem, we're told to determine the condition that will increase the amount of product at equilibrium for the endo thermic reaction. So we're dealing with lush outliers principle here, which tells us that whenever a stress is put on a system, the system is going to try to offset that stress. So we need to see what is going to increase our amount of product for the first answer choice rem moving cl two from the mixture. So we can see here that cl two is one of our reactant. And so if we're decreasing the reactant, it's going to shift towards the production of more reactant. So answer choice A. Is going to shift left and by its shifting left that's not increasing the amount of product. So we answer choice is not correct for be increasing the volume of the reaction. So we see in the reaction that we have two moles of reactant and one mole of product by increasing the volume, we're decreasing the pressure and the reaction is going to shift to the left towards the side with the more moles of gas particles. Okay, so answer choice B is also not correct. Answer choice C increasing the amount of c four H eight c four H A. Is one of our reactant. And if we're increasing the reactant, it's going to shift towards the production of more product. So the reaction is going to shift to the right when we shift to the right that is going to create more product. So answer choice B is our answer choice seat is correct so far and answer choice D. Increasing the temperature of the reaction. If the temperature of the reaction at equilibrium is increased, that means we are adding heat to the system and the equilibrium will shift away from the heat to lessen the amount of heat on the product side. So this is going to shift to the right and when we shift to the right, it's going to create more product. So answer choice D. Is also correct. So the two correct answer choices for this problem are C and D. And that's the end of this problem. I hope this was helpful.
