P(g) + Q(g) ↔ 3R(s) + S(g) ΔH is negative
Which of the following will increase the yield of R?
Which of the following will increase the yield of R?
Using a larger close vessel
Increasing the temperature
Removing some S
Adding a positive catalyst
Forklaring
Since the reaction is an exothermic reaction, the yield of R will be enabled if temperature is decreased. The only way to increase the yield is by removing some of the S produced, while the reactant are being refilled continuously. Option C is the correct answer
