The rate equation for the hydrogenation of ethene C2H4(g) + H2(g)-------------------> C2H6(g) is Rate = k[C2H4] At a fixed temperature, the reaction mixture is compressed to triple the original pressure. What is the factor by which the rate of reaction changes?

Do you know what the equation for the rate actually means? Do you understand the use of the square brackets?
Because the overall order is 2,and the concentration is changed by 3, the rate change will be 3 squared = 9 ( because for 2nd order the rate is proportional to concentration squared)
