The reaction is spontaneous at a temperature of 7281.4 K
As the value of temperature rises, it is decreasing in accordance with the value of ΔG°, according to the value ofΔG° calculated. The value shifts from being more positive to being less positive. It ΔG°at a certain temperature.
It would appear that the value of would be negative, causing the reaction to occur on its own.
The calculation shown below can be used to determine the temperature at which the reaction starts spontaneously.
ΔG°= ΔH°-TΔS°
ΔG° now equals zero.
0 = 180.58 - T 24.8(1/1000)
T= 180.58/0.0248 K
T=7281.4 K
therefore, the reaction is spontaneous at a temperature of 7281.4 K

The answer is
(B),
Solution to your problem is as follow,
Answer:
0.000121 year⁻¹
Explanation:
The half life is defined as the time at which the reactant's concentration reduced to half.
The formula for the half life for a first order kinetic reaction is:
Where,
is the half life
k is the rate constant.
Thus, Given that:
Half life = 5730 years
Where, k is rate constant
So,
<u>The rate constant or decay constant, k = 0.000121 year⁻¹</u>
