∆G = ∆H-T∆S
=20×10^3-(15+273)(.101×10^3)
=20000-(288)(101)
=20000-29088
=-9088 joule = -9.088 kj
Answer:
The value of the gas equilibrium constant Kp is 18.3
Explanation:
Step 1: Data given
Kp= Kc(RT)^Δn
Temperature = 298 K
Kc = 18.3
Step 2: The balanced equation
C₄(s) + 4 O₂(g) ⇌ 4 CO₂(g)
Step 3: Calculate Kp
Kp= Kc(RT)^Δn
⇒with Kp = the gas equilibrium constant = TO BE DETERMINED
⇒with Kc = the equilibrium constant = 18.3
⇒R = the gas constant = 0.08206 L* atm/mol*K
⇒T = the temperature = 298 K
⇒Δn = mol gas phase product – mol gas phase reactant = 4-4 =0
Kp = 18.3 * (0.08206*298)^0
Kp = 18.3 * 1
Kp = 18.3
The value of the gas equilibrium constant Kp is 18.3
No, because plastic cups can be dissolved by organic compounds. Moreover, they are easily melted so a highly exothermic reaction can not be studied using them.
How difficult it is to change an objects motion. Think of a tablecloth; it takes energy to move it from underneath objects on the table, and it takes energy to move the objects themselves on the table.
C. no difference in the electronegativity of oxygen and hydrogen
