For a reaction `R_(1), Delta G = x KJ mol^(-1)`. For a reaction `R_(2), Delta G = y KJ mol^(-1)`. Reaction `R_(1)` is non-spontaneous but along with `R_(2)` it is spontaneous. This means that

A

x is -ve, y is +ve but in magnitude x gt y

B

x is +ve, y is -ve but in magnitude y gt x

C

Both x and y are -ve but not equal

D

Both x and y are +ve but not equal.
