For the hypothetical reaction: a + b > 2c, write an expression that relates the disappearance of a and b to the appearance of c. you can use the word delta instead of the symbol .

Rate expression has been given below

Explanation:

According to the given equation, 1 molecule of A reacts with 1 molecule of B and produces 2 molecules of B at a time.

So, rate of disappearance of both A and B are one half of rate of appearance of B

Hence rate expression can be represented as:

where is rate of disappearance of A, is rate of disappearance of B and rate of appearance of C

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

there is none because earth is stationary and flat.
