Answer #1

1)

By what factor does the reaction rate change if the concentrations of A is doubled?

Since order of A is 0, the rate will not change

Answer: 1.0

By what factor does the reaction rate change if the concentrations of B is doubled?

Since order of B is 1/2

rate will also become (2)^1/2 = sqrt(2) times = 1.4 times

Answer: 1.4

By what factor does the reaction rate change if the concentrations of C is doubled?

Since order of C is 2,

rate will become 2^2 = 4 times

Answer: 4.0

Consider the following reaction which follows zero-order reaction kinetics           A(g) + Catalyst(s) ? B(g)                ?H = -226.9 kJ Notice that the reaction is exothermic, so in a closed system it is possible for this to get out of hand: The reaction releases energy, which increases the temperature, which increases the rate, which makes it heat up faster, which makes it react faster
