Question
WIth active metals to produce H2(g) reacts with CO2(g) to form carbonates All of the above are characteristic properties of acids. 50. Calculate the hydrogen ion concentration in a 85.3 ml solution of iced tea w having a pH of 2.87. gen ion concentration in a 85.3 mL solution of iced tea with lemon 2.9 x 102M B) 2.9 x 10*M) 5 1.3 x 103M 5.7 x 102M D) 5.7 x 104M 51. The following reactions have the stated equilibrium constant values at 400 K. Arrange these reactions in order of increasing tendency to proceed to completion (least completion greatest completion). 1) 2NOCI #2NO + Cl2 Kp = 1.7×10-2 he kel Com Lower Kp 6.2 x 102 K,-1.3×10-s, Kp = 5.9 × 10.5 Faster Faster 10mph 3) 4) 2503-250, +02 2N02-2N0 +02 D) 3Explanation / Answer
50.)
pH = 2.87 = -log [h+]
H+ concentration = 10-2.87 = 0.001348 M
= 1.3 X 10-3 M
E) - answer
51)
t. When Kp >> 1, the reaction goes almost to completion, When Kp << 1, the reaction hardly proceeds.
E.) 3 < 4 < 1 < 2
42)
Kp = [([C] RT) c ([D] RT) d]/[([A] RT) a ([B] RT) b]
= Kc (RT) n
Kc = 2.1 X 10^-2 = 0.021
Kp = 0.021*(0.082*673.15)1 = 1.15 = 1.2
D)------- answer
