At what temperature, in K, does X(l) → X(g) occur spontaneously?
At boiling temperature this reaction becomes spontaneous.
At Tb liquid starts to boil (converts into gaseous phase) upto when it's pressure become equal to atmospheric pressure.
So at boiling temperature liquid converts into gaseous phase
15. Predict whether each reaction will occur spontaneously or not. If it does occur, write a balanced equation. a) Mg(s) + ZnCl2(aq) → b) Cu(s) + AlBr3(aq) → c) Al(s) + CuCl(aq) →
For a reaction to occur spontaneously, the thermodynamic value ∆G must be which of the following? (a) A positive value (b) A negative value (c) zero
What is the density (g/L) of H2 gas at a temperature of 283 K and 0.500 atm? (Hint: One approach is to assume a sample size of 1.0 L.) -0.0107 g/L -0.0217 g/L -0.0434 g/L -93.7 g/L -0.0899 g/L
At what temperature (in °C) does 12.41 g of neon occupy a volume of 12.78 L at a pressure of 1.03 atm? Report your answer to 3 significant figures and do not include units in your answer. ОС -13.5 Use the ideal gas law to help you after first converting to moles. Note the answer asks for temperature in celsius and that the temperature must be in kelvin when using the Ideal Gas Law. K- 273.15 °C
3. Calculate AG° for the following reaction at 25°C. Will the reaction occur spontaneously? How do you know? Explain your answer. NH3(g) HCl(g)-- NH4CI (s), AH° = -176 kJ , AS°= -284.8 J/K
at what temperature does the anneal step of pcr occur?
Write the products for all the reactions below that are expected to occur spontaneously. If there isn't a reaction, write NR Cl2 (g) + 2I (aq) -> H2 (g) + F2 (g) -> Ni (s) + Cu2+ (aq) -> Fe (s) + Ni2+ (aq) -> Cu2+ (aq) + Ag (s) -->
