D O 4. (07.07 MC) What stress will shift the following equilibrium system to the right?
2502(g) + O2(g)
2503(g); AH= -98.8 kJ/mol (3 points)
Decreasing concentration of SO2
Decreasing temperature
Increasing concentration of SO3
Increasing volume

answer; i believe the correct answer is (solid gold);

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
