Which phrase describes a control group?

Calculate Kc for the reaction 2HI (g) H2 (g) + I2 (g)  given that the concentrations of each species at equilibrium are as follows: [HI] = 0.85 M, [I2] = 0.60 M, [H2] = 0.27 M.

The reaction A + 2B → products was found to follow the rate law: rate = k[A]2[B]. Predict by what factor the rate of reaction will increase when the concentration of A is doubled, the concentration of B is tripled, and the temperature remains constant.

For a certain first order reaction the half-life is 14 s. The value of rate constant, k,  for this process is:
