The half-life for the process 238U→206Pb is 4.5×109yr. A mineral sample contains 61.0 mg of 238U and 14.5 mg of 206Pb. What is the age of the mineral? To calculate the age of the mineral, begin by rearranging the first-order relationship between the half-life, t1/2, and the decay constant to solve for the decay constant, k. k=0.693/t1/2 Then, use the following formula to solve for the age of the mineral, t: t=−1klnNtN0 where N0 is the original amount of 238U...

how to solve this? Sulphur trioxide decomposes at high temperature in a sealed container: 2 SO3(g) <--> 2 SO2(g) + O2(g). Initially, the vessel is charged at 1000 K with SO3(g) at a partial pressure of 0.500 atm. At equilibrium the SO3 partial pressure is 0.200 atm. Calculate the value of Kp at 1000 K to 3 decimal places.
