According to the collision model, why does decreasing the temperature decrease the rate of a reaction? Decreasing the temperature decreases the number of collisions that can occur with enough energy for the reaction to occur.
O Decreasing the temperature causes fewer particles to occupy the same amount of space which therefore decreases the reaction rate.
O Decreasing the temperature causes less of the collisions to occur with the correct particle orientation for the reaction to occur.

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
