A decomposition reaction is found to be first order with respect to the reactant. What is the relationship between the rate and concentration of the reactant?

A) The rate is inversely proportional to the square of the concentration
B) The rate is inversely proportional to the common logarithm of the concentration
C) The rate is directly proportional to the concentration
D) The rate is directly proportional to the common logarithm of the concentration

I think it is A, just want to clarify.

  2. Hey, the answer to your question would be

    C) The rate is directly proportional to the concentration

    That's because the "exponent" or, superscript, of the reactant is 1. Thus, whatever value the concentration multiplies by, the same goes for the rate.
