Question
For a reaction R1 , G = x KJ mol-1 For a reaction R2 , G = y KJ mol-1 Reaction R1 is non - spontaneous but along with R2 it is spontaneous This means that
- x is -ve , y is +ve but in magnitude x > y
- x is +ve, y is -ve but in magnitude y > x
- Both x and y are -ve but not equal
- Both x and y are +ve but not equal
The correct answer is: x is +ve, y is -ve but in magnitude y > x
