CHM 2046 Exam 3 UPDATED Exam Questions and CORRECT Answers equilibrium constant - CORRECT ANSWER- Kc=[products]/[reactants] product favored - CORRECT ANSWER- K>1 reactant favored - CORRECT ANSWER- K<1 reaction quotient - CORRECT ANSWER- Q=[initial products]/[initial reactants] at equilibrium - CORRECT ANSWER- Q=K

Vapor Pressure is a form of Dynamic Equilibrium Molecules are constantly moving between phases, but the rate at which the molecules move from the liquid ↔ gas phase is constant Chemical Equilibrium a state in which the rate of a forward reaction and the rate of the reverse reaction are the same as the reaction uses its reactants the forward reaction starts to slow down How is chemical equilibrium reached? reactants and products are still forming when it is reached, just at th...

1(a)   A function, f say, is a set of ordered pairs in which no two distinct elements have the same first entry. If A is a source set of f and B is a codomain of f then we use the notation f : A→B read as ‘f is a function from A to B ’. 4marks f ( x )=x2 1(b) g ( x)=2 x−3 f ( 2 x−3)=∣2 x−3∣2 ¿ (2 x−3) (2 x−3 ) 2−12 x+ 9 4 1 ¿ 4 x 2 mark s 1(c) (i) The Modulus or Absolute Value f...

Reversible process - ANSWER--occurs when the products of the reaction can react to form reactants Equilibrium - ANSWER--state in which forward and reverse processes are occurring at the same rate -no net change in reactant and product concentrations over time Reaction quotient (Qc) - ANSWER--fraction written with product concentrations in the numerator and reactant concentrations in the denominator with each concentration raise to a power equal to the corresponding stoichiometric coeffici...

STP - correct answer 0°C and 1 atm Ideal Gas Law - correct answer PV = nRT At STP, 1 mol of gas will occupy ... - correct answer 22.4 L Characteristics of an Ideal Gas - correct answer 1. Gas molecules have zero volume 2. Gas molecules exert no forces other than repulsive forces due to collisions 3. Gas molecules make completely elastic collisions 4. The avg. kinetic energy of gas molecules is directly proportional to the temperature of the gas Partial pressure of a gas (equation...

For the reaction F2(g) ⇌ 2 F(g), the equilibrium constant at 223 °C is 7.3 x 10-13. If a sample of F2 is heated to 223 °C and allowed to reach equilibrium correct answer: nearly all of F2 will remain unreacted, with a very small amount of F present At equilibrium correct answer: the rate of the forward reaction is equal to the rate of the reverse reaction and the concentration of the reactants and products can be very different For the reaction 2 BrCl(g) ⇌ Br2(g) + Cl2(g), the equi...
