Assume the hydrolysis of ATP proceeds with ΔG′° = –30 kJ/mol. ATP + H2O → ADP + Pi Which expression gives the ratio of ADP to AT
Andru [333]

Answer:

6.14\cdot 10^{-6}

Explanation:

Firstly, write the expression for the equilibrium constant of this reaction:

K_{eq} = \frac{[ADP][Pi]}{ATP}

Secondly, we may relate the change in Gibbs free energy to the equilibrium constant using the equation below:

\Delta G^o = -RT ln K_{eq}

From here, rearrange the equation to solve for K:

K_{eq} = e^{-\frac{\Delta G^o}{RT}}

Now we know from the initial equation that:

K_{eq} = \frac{[ADP][Pi]}{ATP}

Let's express the ratio of ADP to ATP:

\frac{[ADP]}{[ATP]} = \frac{[Pi]}{K_{eq}}

Substitute the expression for K:

\frac{[ADP]}{[ATP]} = \frac{[Pi]}{K_{eq}} = \frac{[Pi]}{e^{-\frac{\Delta G^o}{RT}}}

Now we may use the values given to solve:

\frac{[ADP]}{[ATP]} = \frac{[Pi]}{K_{eq}} = \frac{[Pi]}{e^{-\frac{\Delta G^o}{RT}}} = [Pi]e^{\frac{\Delta G^o}{RT}} = 1.0 M\cdot e^{\frac{-30 kJ/mol}{2.5 kJ/mol}} = 6.14\cdot 10^{-6}

A chemical reaction takes place in which energy is absorbed. Arrange the characteristics of the reaction in order from start to
marshall27 [118]
Endothermic reactions, on the other hand, absorb heat and/or light from their surroundings. For example, decomposition reactions are usually endothermic. In endothermic reactions, the products have more enthalpy than the reactants. Thus, an endothermic reaction is said to have a positive<span> enthalpy of reaction. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed.</span>

The normal boiling point of a liquid is 282 °C. At what temperature (in °C) would the vapor pressure be 0.500 atm? (∆Hvap = 28.5
NNADVOKAT [17]

For a normal boiling point of a liquid is 282 °C, the temperature is mathematically given as

T2=181.55°C\

<h3> What temperature (in °C) would the vapor pressure be 0.500 atm? </h3>

Generally, the equation for the gas  is mathematically given as

ln(p1/p2)=dHvap/R(1/T2-1/T1)

Therefore

ln(1/0.26)=23500/8.214(1/T2-1/555)

T2=181.55^C

In conclusion

T2=181.55°C
