these two questions

A student carried out an experiment to determine the enthalpy of combustion of ethane. Combustion of 229mg of ethane increased the temperature of 75.00mL of water from 25.1C to 40.2C. Calculate a value, in kJmol1, for the enthalpy of combustion of ethane (Hc) in this experiment. Give your answer to the appropriate number of significant figures. (The specific heat capacity of water is 4.18fC1g1 ) A mixture of ethene and hydrogen was allowed to reach equilibrium in a container of volume 250.0mL at temperature, T. Initially, the mixture contained 0.240mol of ethene, 0.0900mol of hydrogen and 0.0305mol of ethane. If the value of K is 0.500. determine the direction that the reaction will shift in order to reach equilibrium
