I have a scenario where the user has to slect the account and redirect to a new vf page but I am not able to pass the account id so that the new page displays the details about the selected account. I have posted the vf page and controller code.

Thanks in Advance!
 

<apex:page controller="pagination" tabStyle="Account">
<apex:form >
  <apex:pageBlock >
  Page No: {!pageNo} <br/><br/>
      <apex:pageBlockTable value="{!Accounts}" var="a" rows="10">
          <apex:column >
              <apex:actionSupport action="{!account}" event="onclick">
              <apex:outputtext value="{!a.id}"/>
              </apex:actionSupport>
          </apex:column>
          <apex:column >
          {!a.name}
          </apex:column>
      </apex:pageBlockTable>
  </apex:pageBlock>
  <apex:commandButton value="Previous" action="{!previous}" disabled="{!!hasPrevious}"/>
  <apex:commandButton value="Next" action="{!next}" disabled="{!!hasNext}"/>
  </apex:form>
</apex:page>
