Question

Suppose you have 1 atm of gas A and 1 atm of gas B. If A and B react to form C with a 1 A: 1 B: 2 C stoichiometry, what will the pressure of C equal?\

Answer 1

Answer – We know the number of moles increase pressure also increase. The moles and pressure are directly proportional to each other. So when 1 mole of A reacts with 1 moles of B there are formed 2 moles of C.

So , both A and B are limiting reactant and moles of C are two.

So pressure of C = 1 atm *2

                           = 2 atm.
