I have been researching these questions for 2 weeks now, I have read my whole Chemistry Book and I'm still at a dead end for an answer.  Could you please *delete me*

1. If a reaction A + B ---> C is second order in A and first order in B, which of the following will cause the rate to increase by a factor of 42?
My choices:
a. double [A] and keep constant
b. double and keep [A] constant
c. double both [A] and
d. double [A], halve

I think the answer is double and [A] constant

2. A very negative value of Gibbs' free energy of formation for a compound indicates that?
a. the substance is thermodynamically less stable than the elements it is made from in their standard states.
b. the substance is thermodynamically more stable than the elements is made from in their standard states.
c. the compound will be formed very quickly from the elements in their standard states.
d. the compound will quickly decompose into elements in their standard states.

my answer (a)
